Many thanks for your efforts.

Because the functionality is now completely non rabbit-specific, they
should not really be in a module with a rabbit_ prefix. The more
reusable parts of rabbit's code base tend to follow this rule.

changes, which I'll send to you off list - I don't think you've already
signed one.
