Description

I suggested doing this in http://tracker.ceph.com/issues/3427.
That issue is about a bug where an image unmapping can get underway
after an open of the mapped device has begun, with predictably
undesirable results.

I didn't have a good test for it though. I've put something
together that I've verified catches that issue. Since it took
a few hours this morning I thought I should record it separately.

I still have some more testing to do but I intend to add this as
a new test script "qa/workunits/rbd/concurrent.sh" in the ceph
git tree.
