Comment (by adamsilverstein):

 > why? if you pass the post, it skips the lookups in `get_post()`

 because I am no longer getting every revision as revision objects to
 generate the list. instead I'm getting only the fields needed for the
 revisions list, avoiding loading the post content, title and excerpt data
 into memory. we don't really need complete post objects to generate the
 list, and getting them causes memory use bloat, especially for large/many
 revisions.
