Comment (by rhaas):

 Attached please find a patch (loose-interaction.patch) which accomplishes
 this. It no longer replicates Carpet's logic but at the price of
 introducing a second function and more #ifdefs. Which one is nicer depends
 on how crucial it is to keep user thorns ignorant of Carpets internal
 logic I guess. Both versions are fine with me (though I slightly prefer
 the first version since it does not require a static variable).
 Alternatively and since I know of several other thorns that could benefit
 from something like this, how about defining (yet another) aliased
 function to return "RunOnLevel(rl)" which returns
 {{{cctk_iteration%do_every == 0}}} or {{{(cctk_iteration-1)%do_every ==
 0}}} depending on whether we are in EVOL or not? Ie. an aliased routine
 that exposes Carpet's decision (but not the logic behind it) to the user
 code in a hopefully controlled manner?
