Log message:
What I hope is the END of the sdl soundserver lagtime, I got rid of the
condwaits once and for all.  They weren't granular enough.

They now use sci_sched_yield.

I changed sci_sched_yield now too, it does a sleep(0) on win32 and
usleep(0) on everything else.  this seems to implicitly yield on both
platforms (well, at least on ia32 linux, that is..)

Test it, and let's see what happens.
