    sbin/mountd          mountd.c 
  Log:
  Fix a long-standing bug relating to the handling of SIGHUP: mountd
  would call malloc, stdio and other library functions from the signal
  handler which is not safe due to reentrancy problems.
  
  Instead, add a simple handler that just sets a flag, and call the
  more complex function from main() when necessary. Unfortunately to
  be able to check this flag, we must expand the svc_run() call, but
  the RPC library makes that relatively easy to do.
