I realise this has moved to a PR but I'm still working through some of 
the areas that are touched in this patch.

Switching the Pipe implementation to use a Unix domain socket on Windows 
is good but it looks like it will try to create a Unix domain socket 
every time, even on editions of Windows that don't support it. Can this 
be changed to try once and fallback to the existing loopback connection 
approach thereafter? Minor nits here but "getServer" returns a listener 
socket so needs a better name. Also in the SinkChannelImpl then it would 
be better to keep the layout consistent and put setNoDelay at the end 
rather than before the constructor.
