  Modified files:
    sys/kern             vfs_subr.c 
  Log:
  Remove the P_BUFEXHAUST flag from the syncer process (leaving
  it only on the buf_daemon process). The problem is that when the
  syncer process starts running the worklist, it wants to delete
  lots of files. It does this by VFS_VGET'ing the vnodes, clearing
  the blocks in them and bdwrite'ing the buffer. It can process close
  to a thousand files per second which generates a large number of
  dirty buffers. So, giving it special priviledge at the buffer trough
  leads to trouble as the buf_daemon does occationally need a free
  buffer to proceed and if the syncer has used every last one up,
  we are toast.
