-Subject: [PATCH] Create a lock on cached_property if not present (#1811)
-
-* Create a lock on cached_property if not present
-
-This fixes #1804 (fixing breakage caused by use of undocumented
-implementation details of functools.cached_property) by ensuring a lock
-is always present on cached_property attributes, which is required to
-safely support setting and deleting cached values in addition to
-computing them on demand.
-
-* Add a unit test for cached_property locking
