Hi Keystone team,

I am writing to ask someone from the Keystone team to give their opinion regarding whether it is safe to run the Keystone wsgi app in multiple threads in the same process.

I see [1] Kolla team allows users to configure the number of processes but not the number of threads.

We in Openstack-Helm have a similar review request [2] and we had a small discussion about this. I would really appreciate it if someone from the Keystone team can give their opinion on [2].

Thanks.
