Steve Loughran commented on SLIDER-270:
---------------------------------------
There's some code that tries to pick a container for release -it doesn't pick a
container that is already targeted for release and which has not yet been
released. It could be that the wrong container is being tagged as for-release,
or something similar.
This should be mock-testable
> Calling flex (down) the second time does not work
