So, the warbling is *less annoying* with my splaudio() changes, but
it's still there, a little.  I'll have to look into it a bit more.  I
also note that I now seem to get exactly the same effect whether
running `mikmod' locally with no network traffic at all or while
running a `ping -f' against the machine -- so I think the ethernet
chip is now out of the loop here.

Lastly, I noticed that if I do:

# dd if=alone.raw of=/dev/sound bs=8k
^C
# dd if=alone.raw of=/dev/sound bs=8k

Sometimes I will get `static' from the second command.  I suspect this
is because the DMA FIFO is becoming misaligned with respect to the
sample size.
