+    """Mixin for handling the astroid cache problems.
+
+    When clearing the astroid cache, some tests fails due to
+    cache inconsistencies, where some objects had a different
+    builtins object referenced.
+    This saves the builtins module and makes sure to add it
+    back to the astroid_cache after the tests finishes.
+    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.
