Sorry to follow upp on my own ramblings, but I'm getting more and more 
convinced that using JACK for internal connections in a modular synth will
not work as expected.

For example, take the patch

JACK -> A -> JACK -> B -> JACK

where A and B are two processing modules.

If A and B are inside the same JACK client, what will happen ?
Will jack use a single buffer for A-out and B-in  (this is what you'd
expect in a modular synth), or will it copy the previous A-out to B-in
before calling your process callback, thereby introducing one cycle
delay ?
