Comment (by lunabyte):

 No fancy caching at all. Pure object cache, on disk.

 The database does update, but the cache isn't refreshed. So you see the
 cached query, with the old data, and not the new one.

 Example to reproduce:

 Edit a page. Click save. When it returns you to the manage page overview,
 click edit on the post again. It looks the same (in the post box content)
 as it did when you went to edit it the first time. (Visual editor is off.)

 Another example. Go in and add some categories from the manage categories
 page. They pop up in the list through ajax, but then click that page
 again. They aren't there. Then, try to make a post. Again, they're not in
 the list in the sidebar.

 Clear object cache (rm -rf *), and all is well.

 This has been observed on several platforms and sites.
