There was a eventlet.monkey_patch [1] when we launch a nova process(like nova-api, nova-compute), but it's invalid under the uwsgi mode. But there are concurrency requirements in the api service, such as, when listing instances cross multiple cells we're using greenthreads and oslo.db does a time.sleep to allow switching greenthreads [2]. So, in this patch we add the monkey_patch in the uwsgi application setup and refactor the monkey patching to use common code.

If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
