    sys/ufs/ffs          ffs_softdep.c 
  Yield the cpu in the kernel while iterating the list of the
  vnodes belonging to the mountpoint. Also, yield when in the
  softdep_process_worklist() even when we are not going to sleep due to
  buffer drain.
  It is believed that the ULE fixed the problem [1], but the yielding
  seems to be needed at least for the 4BSD case.
