The comment in that place in the code says "... that's fine too ... " - It's not fine. AFAIK, since the file descriptor is closed, epoll did not actually remove it - Further down the road, attempts to add fd 14 fail since epoll did not remove fd 14 in the first place.
It seems like libevent delays the call to epoll_ctl, and by the time it actually does that, it's too late. *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
