Francis MB added the comment:
Why is test.support.EnvironmentVarGuard preferable over
distutils.test.support.EnvironGuard (with this one I'm not getting the warnings
below)?
If I change the patch to (not so different (?) as in other tests using
EnvironmentVarGuard):
$hg diff

I get the message:

Warning -- threading._dangling was modified by test_distutils
Using EnvironmentVarGuard as context manager gives the same warning.
