I would be OK with using this implementation strategy as a stepping stone for a lockfree implementation, which would require making this experimental. I agree with @huixie90 that we need to implement this in a lockfree way, and my understanding is that this requires more research cause there is no efficient and publicly available implementation that works on all platforms.
