This is in zmq master branch right? I think we have a nasty race condition here, and I don't think it's mac specific.

But session::process_attach() can delete this engine, while it's still in use in io_thread out_event() callback. Both session setup and tear down are quite complicated, not sure what's the best way to fix this.
