Hi all, I read the paper about the new ghc7 event handling IO manager goodies. This is all very exciting stuff. I didn't know GHC's RTS had these smart async-IO facilities. The paper pointed me at threadWaitRead/threadWaitWrite. While very nice the way they are, I would also like to be able to wait on more than 1 fd until 1 of them becomes available. Would it be possible to create this functionality myself? Or do I need to request it and wait for a new GHC? It looks like the functionality I need is in System/Event/Thread. I think I can manage to write my own version of those functions which then loop through a list of fds, but the original file imports System/Event/Manager (registerFd, unregisterFd_) which I can't do because it's a hidden module. Is there a way around this? Thanks, Mathijs
