On the second thought I guess for Evictor's main job we can simply/directly call
this PostDelayedTask in the Evictor code using ScopedRunnableMethodFactory?  It
doesn't need to carry around per-task / per-invocation info but will need to
continuously work using the evictor's shared status.  (while in the main method
we may still need to post some quota thread tasks)

Changed it and removed QuotaDelayedThreadTask.  BTW, what is the need to post
quota thread tasks?

Ah, failed to remove it.  Removed in the patch set 3.
