Log message:
Revisit 2q queue sizes. Limit the hot queue to 1/20th the cache size up
to a max of 4096 pages. Limit the warm and cold queues to half the cache.
This allows us to more effectively notice re-interest in buffers instead
of losing it in a large hot queue. Discussed and shown with claudio@
and benno@ at tk217
