There are several locks used for chess programs, spinlocks, mutexes etc.

So, as I am currently implementing SMP into FruitFly, would it be worth the hassle of converting the Toga mutexes to C++11 atomic locks?

First question is, what is your goal? Max performance on a dedicated machine? Use nothing but spinlocks. If you are going to compete for CPU resources with other running processes (non-chess processes) then a traditional mutex that spins and then blocks is the way to go... I only care about the former myself, not the latter.
