    sys/kern             vfs_bio.c vfs_cluster.c 
  Log:
  Reimplement B_AGE.  Have it cycle the buffer in the queue twice instead of
  placing buffers at the head of the queue (which causes them to be run-down
  backwards).  Leave B_AGE set through the write cycle and have the bufdaemon
  set the flag when flushing dirty buffers.  B_AGE no longer effects the
  ordering of the actual write and is allowed to slide through to the clean
  queue when the write completes.
