  * Fix a bug in the new scheduler
  If the current thread blocks, we should yield the Capability
  immediately, because the thread and hence possibly the current Task
  are now owned by someone else.  This worked in the old scheduler, but
  we moved where the yield happens in the new scheduler which broke it.

    M ./rts/Schedule.c -1 +2
