Public bug reported:

 Forking processes when a few threads are already running is potentially
unsafe operation and could cause a lot of problems because only current
thread will continue working in child thread. Any locked by other thread
resource will remain locked forever.

We faced with this problem during oslo.messaging development and added
workaround to hide this problem:
https://review.openstack.org/#/c/274255/ I tried to fix this problem in
oslo.service: https://review.openstack.org/#/c/270832/ but oslo folks
said that this fix is ugly and it is wrong way to add workarounds to
common libraries because projects use them incorrectly. I think that is
fare.
