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

[Miller Puckette]

The best way to avoid this is to omit the "-rt" flag (the watchdog is
there to prevent an RT process from locking out everyone else if it
goes in an infinite loop.)  I'd like to know how to prevent its getting
worried when tk goes away on legitimate business (like open panels) but
don't know how to do it and still be sure it's impossible to crash the
machine...

cheers
Miller
