It appears to require multiple users making actions on a wiki simultaneously, and usually when you test a change you're the only user doing anything on your local testing wiki.
Not just some concurrent users. Massive concurrent load.
It's a performance problem. These are pretty much impossible to test for. We don't have a duplicate of our server infrastructure under full emulated load.
