SubjectRe: [PATCH][2.5] mwave updates
Well..  This has nothing to do with the current patch..  It should
still be applied..

At any rate.. I don't believe anybody has done this before.. If you
perform the same excercise without the current patch, you should see the
same result.. I don't see many folks doing this, but it should probably
be fixed... I'll investigate...
