 > Why are we doing each diff as a single ajax request? That seems very
 wrong.

 working on grouping requests...

 idea is to load diffs asynchronously - initial code had all diffs loading
 with a single initial ajax requests, however this can take a while to
 calculate, especially if there are many diffs or there are lots of
 changes. if all diffs are calculated at load, there could be a long delay
 before the page displays at all.  the idea is to allow user interaction
 while the diffs are calculated/loaded - hence the individual requests.

 new patch (coming soon) limits concurrent ajax requests,  a second will
 group requests when there are many revisions to limit the total number of
 requests made by the page.
