The issues seems to be that the test crashes. Which should be fixed 
independently. But in any case, this can happen as it does now, so IMHO we 
should be prepared for that, and not have the whole build fail on that.

Any code in the test to shutdown the cmake server will not be effective if the 
test itself crashes, right?

Is there no way to somehow log by the test execution environment what other 
processes a test triggers and collect them as last resort, if the test itself 
fails to do so? Or could any such processes be somehow explicitly registered 
somewhere. so the test environment can gracefully pick up the parts on a 
crashed test?
