Avoid deadlock between concurrent CREATE INDEX CONCURRENTLY commands. There was a high probability of two or more concurrent C.I.C. commands deadlocking just before completion, because each would wait for the others to release their reference snapshots. Fix by releasing the snapshot before waiting for other snapshots to go away.
