I'm +1 on the feature if it can be turned off, especially in a dev/test
environment.  It certainly does cross the line onto the inconvenient
side when it can cover over race conditions.

For production cases, like deploying openstack in a customer data
center, a sensible retry limit with backoff makes sense to me, mostly
agreeing with what William has already said.

As long as it's discoverable what happened and when -- referencing
#1530840, we should be able to satisfy both use cases (dev &
production).
