There should be a separate asynchronous stop (request) function, notably so
that stop can be requested from within callbacks. And in hindsight, we
probably should have done it that way from the beginning. But we did not have
the benefit of hindsight and we specified stop to wait instead.
We cannot change it now, because we don't _silently_ break APIs. This would
cause huge a number of use-after-free bugs in existing apps.
If you change the semantics, change the name and/or the number of parameters
so that it won't fail silently.
