I would not look at environment variables within the testbrowser code at
all but stick to Python's mechanics to store "global" or local data.

The test runner could grow an option then which can influence that
switch beforehand. (E.g. via a feature) I think that's one of the valid
use cases of "arbitrary" plugins for the test runner.
