[Libevent-users] about exit when using flag EVLOOP_NO_EXIT_ON_EMPTY

[debuguo]

Hello, everyone.
I noticed one new feature added in libevent 2.1, which was the flag of
event_base_new, EVLOOP_NO_EXIT_ON_EMPTY.
BUT I don't know how to exit that event_base loop. even the
event_base_loopexit or event_base_loopbreak seem not work.
Please tell me if you know the answer.
Thank you.
