    Try reducing the count limit from 10000 to 1000.  If that doesn't work,
    try sleeping for 2 ticks instead of 1 tick (with the count limit at
    1000).
Oh, maybe I should try to find out why the stutter happens in the first 
place.  I suspect it to be because the sound card interrupt handler 
doesn't get serviced.  But then -- why isn't the sleep enough?  The sleep 
should schedule any runnable interrupt handler right away.
