Call QuitNow instead of exit(0) to kill GPU process.

This was causing a crash because the global object destructors were being called while other threads were running.

LGTM, though I wonder if this could cause situations where the GPU process may
not exit (and therefore restart) promptly.

Would be good if piman would take a look too.

This LGTM.
If this causes problems, we can use _exit, that skips the global destructors,
but I'd rather try to do the clean termination first.
