Public bug reported:

I am seeing concurrency issues when using mailman 3 in a threaded
application server.

Reading the Storm documentation it states that "Store objects are not
threadsafe. [...] Therefore, the best policy is usually to create a
Store object for each thread which needs one"

In mailman/database/base.py:141 I see a Store being created and cached.

As recommended in the storm docs, Stores should not be cached.
