I'd defer to Hernán and others who may have an opinion. I don't know if 
reusing the test instance could bring problems. Besides, any test I 
write is repeatable, setting Random seeds as needed. I guess you must 
have your reasons to do otherwise...

Maybe you were doing cmd-. to interrupt the process? I don't remember 
[stop] opening a debugger. It is easy to do, though:

terminateRun
     running debugWithTitle: 'Interrupted Test'

If people agree, I can integrate this change.
