Tests for implementations of IReactorSocket.
Generally only tests for failure cases are found here.  Success cases 
for this interface are tested elsewhere.  For example, the success case for
AF_INET is in twisted.internet.test.test_tcp,
since that case should behave exactly the same as IReactorTCP.listenTCP.
