Description

Description

It's very difficult to test our use of CAS in memcached. It's also hard to reason about this analytically due to scant documentation.

Desired behavior/Acceptance criteria (returned value, expected error, performance expectations, etc.)

better testing
more confidence that our concurrency solution is working
