(6) add handler for unix termination signals

it prints a message and calls foo_mem_clean(), swiftly and safely
bringing the runtime down before letting the calling thread it was
ready to exit. note, this is handled through GLib which guarantees
it is only fired once, rather than unwrapped signals that can occur
wildly.
