Something I tripped over recently, that might be nice to change... HANGUP events are always reported, and apparently can't be turned off. In level-triggered mode, if your event loop treats Hangups as lower priority than read/write events, an outstanding Hangup will continue to be signaled every time you call epoll_wait() until it's finally disposed of. It would be nice if Hangups were always oneshot events, regardless of whether the FD was configured level, edge, or oneshot. Certainly we know that the *cause* of a Hangup can only happen once on any descriptor, so it makes no sense for it to be reported more than once.
