Comment (by jwoithe):

 I've finally had some time to look into this.  Not unsurprisingly, I can
 reproduce the original report in so far as jack_delay reports varying
 round-trip latencies for different jackd sessions.  It's early days, but
 from my brief tests tonight it seems that the variation is not due to the
 mechanism I initially thought.  That in itself is an interesting thing.

 It definitely has something to do with the way the fireface is being
 driven because testing with another interface (MOTU Traveler) I don't see
 the latency variation.  I shall continue to ponder this as to whether
 something can be done in the short term to at least minimise the effect
 (whatever it turns out to be).
