   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...)
