so you don't need to lock it to avoid a corrupted value.

It's possible that the ops return junk if all the lock does is avoid corruption. I'm not sure this answers anything.

For starters, does a hash have one iterator per thread or just one iterator? each and possibly keys aren't safe if it's the latter.
