Another piece of terminology to clear up. By "non-blocking foreign call", you actually mean a foreign call that *can* block. As a consequence of the fairness policy, you wish to place the requirement on implementations that such a blocking foreign call _should_not_ block progress of other Haskell threads. The thread-nature of the foreign call is "blocking". The Haskell-API nature is desired to be "non-blocking".
