Because we keep getting mysterious timer related crashes that are only explainable by UAF, thread safety, etc... which always ends up being a top crasher.

If we get data suggesting that these crashes are gone in the next iOS / macOS seed, which we may due to my latest ThreadTimerHeapItem refactoring, we can probably make this debug only again.
