  Log:
  When shutting down the syncer kernel thread, first tell it to run
  faster and iterate to over its work list a few times in an attempt
  to empty the work list before the syncer terminates.  This leaves
  fewer dirty blocks to be written at the "syncing disks" stage and
  keeps the the "giving up on N buffers" problem from being triggered
  by the presence of a large soft updates work list at system shutdown
  time.  The downside is that the syncer takes noticeably longer to
  terminate.
