SVN rev 223770 on 2011-07-04 20:53:55Z by jeff
- It is impossible to run request_cleanup() while doing a copyonwrite.
This will most likely cause new block allocations which can recurse
into request cleanup.
- While here optimize the ufs locking slightly. We need only acquire and
drop once.
- process_removes() and process_truncates() also is only needed once.
- Attempt to flush each item on the worklist once but do not loop forever
if some can not be completed.
