  Modified:    usr.sbin/ypbind  ypbind.c
  Log:
  This is another bug fix that should have gone into my last commit. I
  actually had this done at one point and lost it somewhere along the
  line. Again, this is an honest to gosh bug fix only: no functionality
  is changed.
  
  - After a child broadcaster process dies or is killed, set its dom_pipe_fds
  descriptors to -1 so that the 'READFD > 0' test in the select() loop
  does the right thing.
  
  Since descriptor values can be re-used, failure to do this can lead
  to a situation where a descriptor for an RPC socket can be mistaken for
  a pipe. If this happens, RPC sockets could be incorrectly handed off to
  handle_children(), which would then clear the descriptor from the select()
  descriptor mask and prevent svc_getreqset() from handling them. The end
  result would be that some RPC events would go unserviced. Curiously,
  the failures only happen intermittently.
