I know very little about locale's. /f assigned me a bug http://python.org/sf/1391872 which suggests I run all the tests in a different locale than C. I think this is a good idea, but when I set LANG or LCALL or LCCTYPE in the env't the locale isn't set without me calling locale.setlocale(). Shouldn't we maintain the value from the env't?

the locale is a global program setting, and should only be "activated" when it's actually needed.

my rationale for running the tests with a non-US locale was to increase the chance of catching bugs where the external locale setting affects Python's behaviour.

maybe it would be a good idea to add a "use setlocale" flag to the test- runner ?
