Re: how to catch GHC "no threads to run" exception?

In local.haskell, you wrote:

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. -- http://www-i2.informatik.rwth-aachen.de/stolz/ *** PGP *** S/MIME http://news.bbc.co.uk: The Israeli army destroyed the bomber's family's house afterwards, a military statement said.
