Treat a SocketException like a RemotingException as MS .NET is not wrapping low level socket issues into a RemotingException. (closes: #232)

Yeah this issue is Windows (actually MS .NET) specific as it throws a different exception than Mono does. The error is raised from the .NET Remoting code and doesn't wrap the low level error into a nice RemotingException as Mono does.
