A little more digging shows that qjackctl in Ubuntu 10.4 first tries to reroute audio through JACK and then suspending PA when starting up, so that takes care of PA stepping on JACKs toes. All that actually is needed to get everything working is this line in /etc/pulse/client.conf or ~/.pulse/client.conf:

enable-shm = no

Raine, 

Your suggestion works like a charm. "du -m /dev/shm" shows 1 MB being used, while "ls /dev/shm" shows two (not six) pulse files. Starting qjackctl 
increases "du -m /dev/shm" to 64MB, which remain when qjackctl is killed. On the other hand, I can restart qjackctl at least 5 times without problem 
and without increasing the 64MB of memory. May I ask where you were digging to come up with this?

Fons and Alexander,

This looks like a fairly clean solution without taking any drastic action that might cause upgrade/dependency issues down the road. 

Many thanks at all,

John
