Comment 21 for bug 1789059

https://github.com/mixxxdj/mixxx/blob/dc1b9a1e64ac48e9b926e2afd452a6651a20081d/build/features.py#L495

I have never used it myself and am unsure about the consequences or side-effects. In the best case it results in a minor performance regression.

Using a local build with debug infos would hopefully provide helpful information about what function in Mixxx actually triggers the deadlock.
