This patch corrects the following:

- Patch addresses various rpc.lockd problems.

- Fixes several problems with the network lock daemon, rpc.lockd:

  o NFS mounted file systems may hang.
  o The rpc.lockd program may fail because it loses a message granting
    NLM approval.
  o An NFS mounted file system may hang.
  o The rpc.lockd daemon may crash with a core dump.
  o An error occurs with NFS mounted user mail files. This error prevents
    the files from being locked and prints out the following message:

             cannot lockf

  o An NFS problem may occur. The system displays the following error message:

             NFS error 48 cannot bind sockets

- Corrects two problems, the first change moves locked files from the message
  queue to the held list once. The second change adds code to allow locked
  files leftover from a server reboot, to timeout and be transmitted to the
  server.
