The import line imports TestRunError into the "global" namespeace
of the top level program module *only*. It is not magically
propogated to the other modules imported -- if they want to use
TestRunError themselves, they have to import it, otherwise this
happens:

The cause is whoever wrote the legacy code not understanding
how to program in Python.
