One of the condition to start purging is `hpa_hugify_blocked_by_ndirty` function call returns true. This can happen in cases where we have no dirty memory for this shard at all. In this case purging loop will be an infinite loop. `hpa_hugify_blocked_by_ndirty` was introduced at0f6c420, but at that time purging loop has different form and additional `break` was not required. Purging loop form was re-written at6630c5989, but additional exit condition wasn't added there at the time. Repo code was shared by Patrik Dokoupil at [1], I stripped it down to minimum to reproduce issue in jemalloc unit tests. [1]: https://github.com/jemalloc/jemalloc/pull/2533
