Description

While working on #4384 I have come across several peculiar issues that have led me to conclusion, that something is amiss in the implementation of eventstorage service and generally with implementation of event database access from Flask application directly via psycopg2.

I have found out that it is indeed not implemented in thread-safe manner.

Let's solve by configuration+doc - if using Apache, use process based MPM, if WSGI, configure no threading.

If lack of threading bites us in the future, we'll go for more thorough solution.

So, the configuration was changed on mentat-hub. The only thing to do is to write some information to the documentation, right?

Right. And maybe explicitly fix this in our ansible roles (sigh).

And cuz I'm dork, I did set up mpm_worker instead of mpm_prefork. Sigh, corrected, let's watch it further.
