OVERVIEW

This code is designed to ascertain what thread handles a signal in a
multi-threaded application and whether other threads continue if one
stops.

ts.c - creates a signal handler (SIGHUP) and one additional thread.
The additional thread counts up.  The main thread then counts down.
Sending a HUP signal causes the handler to pause.


HYPOTHESIS

Upon a SIGHUP, the expected outcome is that the main thread will
pause, although it is possible that neither thread would pause and the
signal would be handled by a "new" thread.

CONCLUSION

The main thread handles signals.  Child threads created through
pthreads continue as normal.
