When the CPU is *really* busy running the graphics and other parts of the
game, how do you guarantee that your sound server will not get delayed
in execution to the point where the sound breaks up?

I've found that I need to keep the sound in the same thread as
everything else (at least on single CPU machines) in order to
be able control when it gets called.

The alternative seems to be to crank the priority of the sound task
up above the graphics - but to do that you have to run as root - or
reduce the priority of the graphics...neither seems a very attractive
option.
