since there is no easy way (at least AFAICT) to discover that something bad has happened for the file descriptor and act accordingly. AFAICT any solution would have to be based on a separate thread which either 1) "checks" the FD periodically somehow, or 2) simply lets the thread doing the threadWaitWrite time out after a set period of inactivity. Neither is very optimal.
Either way, I'd certainly expect the sendfile library to work around this somehow such that this situation doesn't occur. I'm just having a hard time thinking up a good solution :).
Well, it is certainly a bug in sendfile that needs to be fixed. I'm not sure how to fix it either. If we can simplify the test case, we can ask Simon Marlow.. - jeremy
