But using deferred cancellation (and using asynchronous cancellation is
strongly discouraged [apart from some very few and limited cases]) you
have no guarantee either, that those threads are canceled, because they
have to wait until they encounter cancellation points. Also I would
argue, that a function, which could hang indefinitely is broken.....
There are always timeouts, or am I missing something.
