Given that we allow creating zero byte fragments, it'd be good to proactively drain them. For example if someone is doing timing instrumentation and wants to know when Network::Connection data is written to the kernel, it could be useful to have a zero byte sentinel.
Risk Level: Low (I don't think anyone is adding zero byte fragments yet)
Testing: new unit test
