WindowMaker doesn't like it if a "sub-procress" re-sets signals that are
used by WindowMaker -- even if said process does it correctly (ie. sets
the signals back to the original handler).
In particular, those signals are SIGABRT, SIGBUS, SIGCHLD, SIGFPE,
SIGHUP, SIGINT, SIGPIPE, SIGQUIT, SIGSEGV, SIGTERM, SIGUSR1 and SIGUSR2
(see wm/src/startup.c) -- which is unfortunate as those are the ones
you're usually interested in while debugging...
Under GNUstep, signals are used by gdomap, gpbs, examples, NSTask,
GSFileHandle, GSTcpPort and UnixFileHandle. AFAIK and AFAICS, only gpbs
re-sets the signals back to the original handler.
