Good to know. In my defense, I couldn't find anything in the manual that
mentions "c" as the module to look in for those functions...

Any thoughts on my other question: if there are a variable-sized set of
dynamically-launched gen_fsm's using a particular module, assuming most/all
of them are idle or will be momentarily, is there a recommended way to
propagate a code upgrade across all of them?
