Do you see all 4 jack threads now?

Woop, there it is. Thanks. I see 5 actually, one -71, one -81 (watchdog?), and the rest 20. Running Csound with its --sched=N flag, I also see two csound processes, one of which is -70 and the other 20, no matter what value I put... time to take that up with the Csound list I guess.

Thanks guys.
