There is a physical as well as a psychological barrier to this running fast and jumping long and high business. Once you know the mark, you are going to try your best to beat it, but you will not go too far above and beyond it.

Breaking the record by a big margin in athletics has happened before. It always does when there or two or three athletes who are good enough to break the world record, because it calls for the extraordinary.[/quote]

Eg: Bob Beamon's record of jumping over 29 feet. Jesse Owens' record of just over 26 feet had stood for nearly 30 years. Then two athletes came-along and absolutely shattered it. Ralph Boston and Bob Beamon. Beating the record by nearly 3 feet (thats about 100 CM - 1 Meter) is a bigger margin than what Bolt has managed in the 100m sprint.
People thought Bob Beamon's record will never be beaten. Carl Lewis pissed about in his 20s just doing what was needed to win the gold. But when Powell, and that Russian jumper came along, Lewis surpassed Beamon's record. He was nearly in his 30s then. Unlucky for him, Powell bettered him in the same meet and in his very next jump. In the end, the unsurmountable Bob Beamon record stood for lesser years than Jesse Owens' 26 feet record, that is very easily surpassed in present day.
Bolt's record will also be broken, and if there are two or three men around capable of beating Bolt's mark at the same meet, i would expect it to fall by a big enough margin too. That would not take any thing away from what Bolt achieved and they can't be considered greater Athletes than Bolt. Better may be, but they were better because Bolt had set the bar high and challenged them to be better. So the improvement is a product of time, rather than ability.

Of course, I agree with a lot of that. But as you point out, large margin breakings of the long jump record were not unprecedented. Boston and Ter-Ovanesyan destroyed Owens's record, and then Beamon completely destroyed theirs (although altitude obviously comes into play there).
I don't think, either as a discipline or as a competitive field, the long jump can be compared to the 100m sprint though. Far more athletes take part in the sprints, and in the modern era (i.e. when training and support facilities have taken advantage of cutting edge techniques and technology - say the last 20 years) a standard natural progression of times can be clearly established. The long jump is now almost a fringe event. The additional effort of sprint-specialising in very deep modern fields means that sprinters rarely double up as jumpers anymore, and there are less specialised jumpers (perhaps a result of it not being a glamour event anymore, and of the kind of athletes who might have previously chosen to specialise in jumping - sprinters who were quick but not quite quick enough - nowadays being attracted to the riches of other sports) which means it is a difficult discipline to historically evaluate. If you remove jumps at Mexico City, El Paso, and Darachichag (all 1000+m above sea level) then there have only been three jumps over 8.70 since Powell set his record. It is a discipline given to freak results simply because there is no standard 'baseline' established by continuous strong competition. By comparison, the ten fastest 100m sprinters ever all clocked their PBs within the last 20 years, and top four are running right now.
I believe where Bolt stands out is that he he not only competes in probably the most hotly contested track discipline, and the one with the finest margins due to its obvious time limits, but he broke the existing records in a way that had never been done before in the 100m. Not even close. He is currently competing with two other men who are faster than anyone else ever, and yet they cannot come within a tenth of a second of him. Like you said, when Powell's record shattered the existing one he was being pushed by the other great jumper in history, Lewis.
Even with other great sprinters, Bolt is still a full tenth of a second faster than anyone else. No other 100m athlete in modern athletics has held such an advantage. And this is just looking at the raw data. There are other things that make Bolt remarkable. He is 6'5'', which makes no sense for a sprinter. His technique is a complete mess, with his thighs often 'crossing' over himself, meaning he is incredibly inefficient in how he uses his own power.
I think the only other athlete who comes close to him is Michael Johnson, in terms of dominating his field, and he was remarkable because he perfected his technique, changing the way people thought about running. And yet Bolt has smashed his remarkable record too. It's scary to think what he might do if his technique can be altered to improve his speed even more.
Regardless of us coming to differing conclusions, good discussion.
