Returning an error from the freeze operation makes sense, but for the
unfreeze I don't see the point.  You must however change all existing
instances to actually return a value (even if it's always 0 for now)
to avoid breaking git bisect.

If you touch all instances anyway, it would be nice to rename them
to freeze / unfreze as the current names are more confusing.
