Description (last modified by Matej Spiller Muys)

In the past python-memcached was removed from Django (4.1).
https://docs.djangoproject.com/en/5.0/releases/4.1/

However https://github.com/linsomniac/python-memcached/releases was resurected with 3 released in past month solving both hacks needed in Django:
https://github.com/linsomniac/python-memcached/issues/159
https://github.com/linsomniac/python-memcached/issues/170

Commit that deleted python-memcached:
https://github.com/django/django/commit/05f3a6186efefc9fca2204a745b992501c6fd91f

Why is python-memcached interesting today is because of HUUUGE performance degradation:
https://github.com/pinterest/pymemcache/issues/478

Basically pymemcache get_many is very slow because it send the request to first sever wait for response, then to second server waiting for response.
But python-memcached first sends the requests to all servers and then waits for responses making it number of memcached servers times faster.
