We also find ourselves writing this "behaviour" quite often (though without
many of the nice features you describe here). Is this something which might
be abstracted from your proprietary code and contributed to the erlang
community (perhaps as the first of a growing pool of new R8 behaviours)? It
would certainly be a valuable addition to the contribs site.

Thanks and Rgds,
