A minimal example would be extremely helpful.
Corinna can answer questions about limitations in the current implementation.
But there is a new implementation under development. It's in the topic/af_unix
branch of the Cygwin git repository if you're interested in looking at it.
Corinna began working on this a couple years ago, and I've recently been trying
to finish it. I've made quite a bit of progress, but there's still more to do
and undoubtedly many bugs. So any test cases you have would be very useful.
