[Zope-dev] ThreadedAsync.LoopCallback.register_loop_callback in Zope 2.7

Does anyone know what is the replacement for ThreadedAsync.LoopCallback.register_loop_callback in Zope 2.7? The problem that in 2.7 asyncore is not started using asyncore.loop. Instead it is manully polled in Lifetime.py. Therefore all callback that are registered via ThreadedAsync.LoopCallback.register_loop_callback are not called.
