Actually, that's not entirely correct. I've been talking to Paul about
this. The xruns created by exiting clients is due to jackd having to
rework it's internals. When doing this reordering, jackd has to lock the
data it's modifying and sometimes (very often) there will be an xrun
because the audio thread is waiting for the lock to be released.

In short. It's not the clients fault, it's jacks' fault.
