In 10.6 you can also do this by setting a dispatch queue on which you want a
block invoked when a signal comes in. If you give it the main dispatch
queue, that's like installing on the runloop of the main thread.
See <dispatch/source.h>.
This is also nice because it's in _addition_ to signal handlers, not a
replacement for signal handlers, and more than one thing can register to be
notified about the signal.
You still have to register a signal handler to avoid having the signal kill
your app.
