Yes - I agree.  My 'SL' sound library (part of PLIB) is non-threaded and
does mixing in software - with programmable latency.  You choose how much
sound it creates on each 'update' call - and it's your responsability to
call 'update' again before that time elapses - or else you'll get a gap
in the audio.

Crude - but it keeps the latency under control (Esound is bad at that -
so is MikMod - but to a lesser extent).

Yes - you are at the mercy of the kernel's scheduler - which could
do all sorts of nasty things to you.
