[concurrency-interest] Propagation of signals to non-interrupted thread

I rediscovered this spec:

      * <p>An implementation can favor responding to an interrupt over
normal
     * method return in response to a signal. In that case the
implementation
     * must ensure that the signal is redirected to another waiting thread,
if
     * there is one.

but this is an "Implementation Consideration" and it could be clearer that
a thread returning abnormally from await cannot cause a lost signal.
