 In [changeset:"30511"]:
 {{{
 #!CommitTicketReference repository="" revision="30511"
 Improve performance of post revision order test.

 `test_revision_order()` was written ([28541], #26042) to ensure that
 revision
 order was properly preserved in two different cases: (1) where the
 post_date
 varied (in which case the revisions would be sorted by post_date DESC) and
 (2) where the post_date was the same (in which case sorting would fall
 back on
 ID DESC). In an attempt to ensure that both of these scenarios arose in
 the
 context of a single test, 100 posts were created. We can make the process
 far
 more efficient by manually creating the revisions with the post_dates
 explicitly declared, and splitting the two different cases into two
 separate
 test methods.

 This test was previously the single worst offender in the entire suite,
 taking
 upwards of 15 seconds to run. All that most maddens and torments; all that
 stirs
 up the lees of things; all truth with malice in it; all that cracks the
 sinews
 and cakes the brain; all the subtle demonisms of life and thought; all
 evil, to
 crazy Boone, were visibly personified, and made practically assailable in
 `test_revision_order()`.

 See #30017.
