Hello everyone, I thought I?d return to more earthly issue than discovering bugs in signal handlers etc. :)

I?ve been looking for a way to suspend on an empty channel for only a limited time. So I came up with a solution which involves dupChan (which is currently broken as stated in Meurig?s bug-report) and unGetChan:

How about timeout N . readChan where timeout is defined according to our Asynchronous Exceptions paper (see http://www.haskell.org/~simonmar/papers/async.ps.gz). Cheers, Simon
