Patch Instructions:
We've implemented parallel cache rebuild protection in 5.2.0-B1 by setting lock before creating new cache. This ensured that all other requests were receiving old cache version or just waiting for a lock to be released.
However I've found a bug in that system too, when multiple visitors, who encountered a missing/outdated cache would set lock in parallel and start rebuild process. This of course would be slightly smaller number of parallel rebuild requests then without protection added in 5.2.0-B1, but still needs to be fixed.
