Comment(by dsd):
I patched tamtam, changed to the test kernel and ran my unscientific
patch. underruns-per-minute reduced from 92 to 76. Then I detatched the
screen session and close the terminal, and observed 16 underruns per
minute (vs 8 from my previous measurements). 2.6.22 still seems to win
hands-down on these tests.
However I then launched TamTamMini from sugar, started a drumbeat and
played a continuous tone on an instrument for a minute or so. Didn't hear
any imperfections. So perhaps we have reached the stages of being "good
enough"
