This is a good point that I hadn't thought of.  Seems like it may be
very difficult, on the other hand if you are going to provide "execute-only"
protection, it had best be foolproof.

I still contend that A)  we need a more usable execute-only (likely not
possible given that "foolproofness" is a requirement) and B) some
documentation would've been nice...
