• adding a test

@dmlloyd: is the test appropriate here for the client. There is no tests so far. Maybe this is too simple and some more "integration" kind of test would be better? Or no test at all?

[dmlloyd]

I'd say the test is not good, as sleep is fairly unpredictable and also not desirable in tests in general; I think that static analysis is good enough for this change, but if we ever did want to do a white-box test, byteman would be the way to go. In general though I think white box unit tests cause us more difficulty than help.

@dmlloyd yeap, I pretty agree. It was not a good addition to the project. I left only the fix if that is ok from your point of view.
