I see. Of course, how silly of me, killThread is asynchronous, it only waits until the exception is raised in the receiving thread, but it does not wait until the thread is really killed. The documentation does not seem to mention this explicitly.
Now, what would be the clean way to make sure all threads are indeed killed before the process quits? I tried to add another MVar that gets set after the thread handles uncatched exceptions (so something like bracket (forkIO a) (putMVar quit ()) return) and the code that calls killThread then does takeMVar quit, but this did not solve the problem.
I'm not sure I understand what the "problem" is – if the process has died, why do we want to kill threads? Bob
