Your JACK process() callback is invoked in a special realtime thread
created within your application process during jack_activate(). The
JACK engine causes this thread to run in each client process once per
period.
If this is not clear, then we need to beef up the JACK documentation.
I guess that goes without saying, anyway. ;-)
