It's not my app, so it's difficult to install signal handlers.


I guess Force Quit sends a SIGTERM before it sends SIGKILL.

I am not convinced that the app's signal handling is in
good order, and the signal handler would cause some confusion in the
stack trace. I would prefer to leave the faulting program's
execution environment unaltered by my diagnostics.

(Certainly a solution that works for all apps is more along the lines
of what I am looking for than a solution that works for just one. But
I suppose an LD_PRELOAD -- err, I mean DYLD_INSERT_LIBRARIES -- of a
signal handler is a possibility if the more general solution doesn't
pan out).

THanks.
