We do have cross-platform locks on the frontend, so we could use those
for now if needed. I don't think this needs atomic for performance
reasons and once we have atomics on the frontend it should be easy to
swap out the a lock for an atomic operation.

I think we are ready, see this thread[1].
We'd still need a MacOS version of stdatomic.h though before we could
rely on it.
