> Having some sanity checks on worker side is helpful to avoid deadlock caused
> by invalid message. For example if the message is malformed, the worker could
> wait for an unreasonable amount of data - if we are unlucky, there won't be
> any errors.
> Checking number of configurations is safe, effective and fast - we should do
> that.
