Thats fine, but the requirement does call for limiting the number of
listeners (see Balking), which would turn away threads when the limit is
reached.

It feels like it would be irrelevant to register a single thread more
than once. I assume that you are tracking which threads are listening on
a EventSemaphore and can detect this? If so, the question remains, is it
an error or intentional usage by the user?
