Sadly, one was a tcp listener, which means if I restart my application the bind() fails when I create an instance of a TcpListener. I'm curious if anyone can confirm the windows/.net behavior for this situation. As far as I know win32 handle inheritance is off unless specified, which leads me to believe that all fd's should be set close on exec by the mono runtime on unix variants.
