The unix socket file is just a faster replacement for tcp and priv  
ports when on the same machine as the server. I wrote that code years  
ago in the 2.1.0 days.

The server is listening on unix, tcp, and udp sockets. The clients and  
moms select the method.

I don't know why your's is hanging. Do some stracing on the server.  
Attach a debugger and see where it is.
