I agree with the sentiment, but thinking of it from a user's p.o.v.
I would be mighty annoyed if I upgraded from 2.9.2 and 2.9.3 and
found that tests in package foo were broken by tests in package bar
only because of changes in package qux.  Test pollution bugs can be
real maddening time-wasters.

Upgrading to 2.10 is another story ;-)

I may try eradicating os.environ usage from Testing on my trunk
sandbox and see what else breaks...
