In my recent tests, it appears as though it is not possible to 
successfully connect via two Unix Domain sockets from one client 
application to one server application.

Specifically, if I create a server which listens on a Unix Domain socket 
and a client, which attempts to connect() twice, both seem to lock up. 
This is not the behavior under Linux.

I will be happy to work up a minimal example if it is helpful in 
tracking this down. I wanted to start by asking whether this is a known 
limitation and/or if there is something about the Cygwin implementation 
that makes this sort of thing very difficult.
