STABLE12-rx-fix-resource-starvation-problem-20011229

This patch fixes a resource starvation condition in Rx.  The
  problem arises, for instance, when more than 4 daemons try to
  prefetch chunks of the same file at once.  The fifth daemon is
  stuck in MAKECALL_WAITING state, never getting a chance to run,
  because the other 4 daemons never yield to the scheduler after
  releasing the call, and just grab the call back again.
