will have to use multiple threads. A single thread does not need to have
such a constraint.

> I think you misunderstand the point. The implementation might not know
what kind of constraints you want to put on it. In fact, it is possible
that you want to put multiple things under the same constraint. For
example, you might want to limit the number of concurrent http calls in
your application, and there could very well be independent things making
such calls. You don't want to pass around naked semaphores.
