True, as you might end up picking up some old stuff that was lying around 
otherwise.  Gah.

It would be nice to make this 100% consistent, and even better to say that 
'all tests runs need to -MTestInit on the command-line'.  That way if you 
needed to do anything special you only have to modify rather 
than every individual test script.

As I said, I think factoring it out would be even better.
