Comment (by adamsilverstein):

 [attachment:34560.8.diff] is an alternate approach, further reducing the
 query:

 * Construct a WP_Revisions class when revisions are used
 * Runs a single query on creation, storing revisions details, revision
 count and last revision id (all needed for the post edit screen)

 @pdfernhout Can you try running your tests again with the latest patch?
 Thanks!
