RE: [Libevent-users] Multiple tcp client connections in single thread with using libevent

["Kelly Brock" <Kerby@xxxxxxxxxxx>]

That looks like the basic outline but for a single thread I would suggest
building the buffer events with BEV_OPT_DEFER_CALLBACKS so the callbacks are
routed into the main thread.  Otherwise the callbacks can be called from the
worker threads directly and you could have a lot of threading fun to deal
with.
