test: no threads to run: infinite loop or deadlock? My problem is that this behavior is actually desired, but how do I catch this exception and do some bookkeeping (closing external IO, etc.) and then a proper exit?

You can wrap the `takeMVar' with Exception.catch. Note that Prelude.catch won't suffice.

Since I have 3 threads waiting on takeMVar, do I have to wrap all of them with Exception.catch? Regards, .paul.
