rx-avoid-unnecessary-wakeups-20011225

"This fixes a livelock condition introduced in my earlier
  resource starvation patch; apparently I had erred too far
  on the side of "wake up just in case".  The livelock bug
  is exhibited when running 10 fsstress processes at once;
  if many processes are waiting for a new Rx call, they get
  stuck in an uninterruptible kernel loop waking each other
  up."
