[Rodolfo Alonso <2091538@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

If the method ``eventlet.monkey_patch()`` is called more than once,
because of [1], present in eventlet 0.37.0, the existing RLocks are
upgraded. This leads to an issue in the oslo.messaging library with
using ``threading.Condition()``, based on RLock.
