   Mark, try the previos patch from Kostik - the one that does the one
tick msleep. I think you'll find that that one does work. The likely
problem with the second version is that uio_yield doesn't lower the
priority enough for the other threads to run. Forcing it to msleep for
a tick will eliminate the priority from the consideration.
