Libev actually pinpoints the faulty fd and tells the callback, which
belongs to the part of the code that actually created the event watcher in
the first place.

libevent doesn't allow you to do that. so even when errno tells you ebadf,
you can do nothing about it, because you cnanot identify the event watcher
responsible for it.
