  Modified files:
    sys/kern             vfs_bio.c vfs_cluster.c 
    sys/nfs              nfs_vnops.c 
  Log:
  Fix lockup for loopback NFS mounts.  The pipelined I/O limitations could be
  hit on the client side and prevent the server side from retiring writes.
  Pipeline operations turned off for all READs (no big loss since reads are
  usually synchronous) and for NFS writes, and left on for the default bwrite().
  (MFC expected prior to 4.3 freeze)
