"""Mixin for handling test isolation issues with the astroid cache.
When clearing the astroid cache, some tests fail due to
cache inconsistencies, where some objects had a different
builtins object referenced.
This saves the builtins module and TransformVisitor and
replaces them after the tests finish.
The builtins module is special, since some of the
transforms for a couple of its objects (str, bytes etc)
are executed only once, so astroid_bootstrapping will be
useless for retrieving the original builtins module.
