More on the EngineLifecycleTest

[Benson Margulies]

A maven run on Windows just had a failure for me that seems to suggest a
possible explanation of all this. I added a test that would fail if the
shutdown sequence left the server accepting connections. It passed in
cruisecontrol and on linux, but failed on Windows. Which may be OS
dependent, or may indicate some piece of unpredictable behavior.
