Once upon a time, we only support accounting thrashing of page cache.
Then Joonsoo introduced workingset detection for anonymous pages and we
gained the ability to account thrashing of them[1].
So let delayacct account both the thrashing of page cache and anonymous
pages, this could make the codes more consistent and simpler.
