It seems a simple way of building the "mult" solution as a composition of the existing primitive(s), here "add". But agreed, that I would not find the tradeof acceptable either.

Forget the locking and data race problem...I think about the massive performance problem.

It turns multiplication into O(n) instead of O(log n). `mult 2000` would take 2000 times longer than `mult 2`.

Imagine being able to DoS a server just by asking it to multiply two numbers.
