Actually, I've given up on doing the ONC suspension change; it was too much
work to torque everything around to support it on both TCP-based networking
configurations.

As for yp_match(), there isn't any way in the YP interface to make this suspend
or be non-blocking, so you won't be able to do anything very easily inside the
server.  The best I can think of is to make major changes to the server, to
fork a special yp_match-calling process at boot-time and to communicate with it
via a UNIX pipe, similarly to the way name-lookup is handled.
