BTW, I think that the idea that let-binding a dynamically-scoped var is
cheap is wrong.
It's basically only cheap when lexical-binding works as well ;-)

So regardless of whether we can speed it up like Eli did just now (by
only looping over the live buffers), the org-scan-tags code that
let-binds it within a tight loop should be fixed.
