Yeah, I was staring down that alleyway and thought, there must be something
better. 'Twould be nice if we had a port_close/2, that could take an option
to choose between killing or detaching from the OS process. But I guess
that's tricky, 'cause ports are so versatile.

Thanks for the link to the CouchDB approach, I might head down that route
after all.
