Doesn't seem like those should be mutually exclusive, though the habits involved are quite opposing and I can definitely believe they're uncommon.
E.g. GC doesn't need to be precise. You could reserve CPU budget for GC, and only use that much at a time before yielding control. As long as you still free enough to not OOM, you're fine.
