Comment 12 for bug 1812672

This is an interesting one and proving difficult to debug. It seems like the overrides in _MemcacheClient are having unintended side-effects with python3. I'll look some more tomorrow but for now adding upstream to the bug. I wonder if we can get Alexander Makarov to take a look as he added this code segment way back in 2015.

class _MemcacheClient(memcache.Client):
    """Thread global memcache client

    As client is inherited from threading.local we have to restore object
    methods overloaded by threading.local so we can reuse clients in
    different threads
    """
    __delattr__ = object.__delattr__
    __getattribute__ = object.__getattribute__
    __new__ = object.__new__
    __setattr__ = object.__setattr__

    def __del__(self):
        pass
