[PD-dev] pd .36-0 "watchdog signaling pd..." on OSX

[Miller Puckette]

Actually the watchdog itself is even higher priority than Pd.  However,
I tried to set it up so that the watchdog refuses to let the GUI
get locked out (even by someone lower priority than Pd) so that you can
always "quit" from the GUI.  So Pd "pings" the GUI, and relays its returning
pings to the watchdog.

cheers
Miller
