I think Eric already mentionned it, but I don't remember the conclusion
and can't find it in the archives. Wouldn't it be cleaner to actually
remove the detached head from the array (do "ref_list.index -= 1"
instead of "index -= 1", and possibly free() what needs to be freed?

I think Michael Haggerty mentioned something along those lines...

Specifically, I think you're referring to [1] (?).
