/* Authors: Jukka Virtanen <jtv@hut.fi> and Peter Stout <pds@cs.cmu.edu>.
A simple client to make GDB (versions 4.4 and later) on Mach 3 return
to the command level when it is waiting for the inferior to stop.
Actions: Lookup the send right to the GDB message port from the
NetMsgServer.
Send an asynchronous message with msgh_id
GDB_MESSAGE_ID_STOP to that port.
