However I can create strange scenarios where there would always be
SA LWPs around with the best priority. (Even without resorting to nice)
LWPs in the global queue would never get a chance.
This is why I used the "theoretically" qualifier ;-)
FWIW, with christian's patch i had semi-regular hangs when using
multiple SA-using processes....
i haven't tried stephan's latest incremental patch, but the previous
update appears to have made 'xmms' unstable. it's crashed a number
of times, the latest just a moment ago after it had run for only a
couple of minutes... i will be trying the update shortly (the box
has been busy...)
