@breed @fpj btw -- sorry for the confusing code. `zoo_aremove_watchers` is
sui generis given that it's the only public method that can return `ZOK`
without scheduling a remote call (for which then, the callback would be
naturally dispatched). Thus, this horrible hack of calling
`notify_sync_completion()`.
