Bruce Evans 1856afe955 Sleep on a better address to wait for output to drain out of the
hardware.  Set the sleep-on flag for the address so there is more
than a small chance that the sleep address is actually used (this
used to work by timing out).  Don't bother clearing the sleep-on
flag after a timeout here or elsewhere since leaving it set just
generates a few null calls to wakeup().
