Apparently that was the case.  You learn something new every day...

My problem isn't with xruns, but instead with pd signalling DIO errors. 
Even with a period of 512 (running a Delta66), I still get the
occasional A/D/A sync error from pd.

One other question - how do I specify 4 inputs/outputs with jack? 
Changing the options in qjackctl throws an error.  Thanks again!
