Excerpts from Bardur Arantsson's message of Tue Feb 16 22:57:23 +0200 2010:
As far as I can tell, all nonblocking networking code is vulnerable to this issue (unless it actually does use threadWaitRead, obviously :)).
There are a few easy fixes: 1) socket timeouts with Network.Socket.setSocketOption 2) just make your server code have timeouts in Haskell This cannot be fixed in the sendfile library, it is a feature of TCP that connections may linger for a long time unless explicit timeouts are used. So just document it and in your code using sendfile wrap it in an application specific timeout. - Taru Karttunen
