Review comment:
I think it helps by avoiding the questionable pattern
[here](https://github.com/python-zk/kazoo/blob/master/kazoo/recipe/watchers.py#L161)
which might be having some weird interaction with the rest of the codebase -
at least we certainly won't see the TypeError now even if the parameter is junk
