For example making use of the Python API, AFAIK, there is no interface where you can run a bounded number of instructions if `lldb.SBThread.StepInstruction` is not guaranteed to return (the current hack around it would be run this in a separate thread with a timeout).

This seems entirely reasonable.  It would be good to get a test case so somebody doesn't inadvertently change the behavior.
