* mode since the datagram transmission code assumes that its socket is created in its
* own thread. Due to the automatic proxying, this assumption is incorrect, because of
* Qt's behind-the-scenes magic.
*
* However, TCP mode uses Qt events to make sure packets are sent off from the right
* thread, and this is what we utilize here.
*
* This is probably not even something that should even be taken care of, as proxying
* itself already is a potential latency killer.
