Title: Add SIGQUIT handler

The handler call pool.terminate(), therefore stopping any running workers. This is better than calling SIGKILL or SIGTERM which leaves workers running. If used with ACKS_LATE, the tasks will be run again when the worker is restarted. Not sure if this should be documented somewhere, as I didn't find where the signals are documented.
