- Replace m_FlushWakeup with a call to the router's god mode pump method. m_FlushWakeup apparently isn't enough to get things out, and we can end up with incoming packets that don't get properly handled right away without it. - The shared_ptr around the ihophandler queues isn't needed and is just adding a layer of obfuscation; instead just exchange the list directly into the lambda. - Use std::exchange rather than swap - A couple other small code cleanups.
