I don't think merging tests that are showing failures, then blacklisting
them, is the right approach. And as Eric points out, this isn't
necessarily just a failure with Ceph. There is a legitimate logical
issue with what this particular test is doing.

But in general, to get back to some of the earlier points, I don't think
we should be merging tests with known breakages until those breakages
can be first addressed.
