I used your code with a few changes to allow passing in the handler names as
startup data (and fixing the loop call arity). Fantastic, thanks.

Out of interest, why did you choose to implement this as a 'made up'
behaviour rather than using gen_server. Is the reason performance /
simplicity, or something subtle to do with the functionality of the startup
mechanism which can't be achieved using standard behaviours.
