Twisted doesn't exit with proper exit code after SIGINT

[jknight]

After receiving a SIGINT, twisted should exit with a SIGINT result code.
It should do this by exiting with:
 signal.signal(signal.SIGINT, signal.SIG_DFL)
 os.kill(os.getpid(), SIGINT)
after shutting down the reactor.
Either that, or re-raise a KeyboardInterrupt, which would let a future version of
python return the right exit code to the OS. (I submitted python bug 1054041 for this too).

This is something twistd could do (I'm guessing that's what you meant).  I don't
think reactor.run() should, though.  Perhaps it could return status information,
though.
