I want to do as little as possible. :-)

Part of the problem is that the non-audio thread goes to the network
which means blocking, which means I can't just do it all within
jack_process().

Thanks to all your comments and questions I think my head has cleared. I
will use a ringbuffer between jack_process() and the network thread, and
emulate that when using ALSA. Someday, when jack starts itself as
needed (as I understand is planned), I wouldn't need to support ALSA.
