-# This is a variant of the very old (early 90's) file

-# trying to import the same module "at the same time".
-# There are no pleasant failure modes -- most likely is that Python
-# complains several times about module random having no attribute
-# randrange, and then Python hangs.

-# Tricky:  When regrtest imports this module, the thread running regrtest
