CompressionOverNetworkTest fails intermittently under Hudson

This test fails intermittently on Hudson. There are 6 similar test cases in this suite, and any one or more of the cases can fail. As far as I can tell the failure is caused by a connection refused when the test setup tries to connect the local and remote broker instances, but I'll have to look into it later.I'm going to exclude this for now to try to get the rest of the suite to finish successfully.
