Squeak's sound playing isn't necessarily regulated to real time.  Even a
lot of oscillators used in *clocks* aren't all that accurate; I'd expect
the oscillators used in sound cards are even less precise.  Given this
situation, synchronizing against the sound seems like a fine approach.

Synching everything against a real clock would be even better.  However, that
means, I would think, stretching or compacting sound buffers compared to
how fast the sound device actually seems to be running.  Doable, but it
takes some work.


Anyway, synchronization of some sort is definately needed.  Especially
let's not forget slower machines, or even fast machines that have a lot
of BouncingAtomsMorphs on the screen.
