  * Fix another subtle shutdown deadlock
  The problem occurred when a thread tries to GC during shutdown.  In
  order to GC it has to acquire all the Capabilities in the system, but
  during shutdown, some of the Capabilities have already been closed and
  can never be acquired.

    M ./rts/Schedule.c -1 +15
