I have to perform another runReaderT when forking? Or is there a way to get the ReaderT environment automatically carried over to the newly created Set B thread?

This is an unavoidable pain as far as I know. It would be nice if forkIO were defined in terms of MonadIO: forkIO :: MonadIO m => m () -> m ThreadId (Same with forkProcess.) I haven't thought too hard about it, but it seems that it should be possible. Andrew
