detach_partition clears cache, but the model partitions still holds partitions that were detached.

I don't know your exact situation, but my guess is that you have multiple instances of your Rails app?

From the readme:

Note that caching is done in-memory for each process of an application. Attaching / detaching partitions will clear the cache, but only for the process that initiated the request. For multi-process web servers, it is recommended to use a TTL or disable caching entirely.

It happens in rails test. I guess due to rails test parallelism the caching issues occur. But I tried to disable caching for test environment and still the issue occurred intermittently.
