1.0.37.14: fix the other half of the WAIT-ON-SEMAPHORE buglet

 * ATOMIC-DECF doesn't do any good if the other write isn't atomic as
   well: even though we are always holding the lock while incrementing
   the waitcount, the possibly unlocked but atomic decrement means the
   increment needs to be atomic too.
