Ok, even better.

That said, the commentary about "why is p.._alloc_track() in such a
core header file, when it's only used by two special cases" is
probably still true regardless of the 5-level fixup header.. I assume
Mike didn't do those kinds of changes?

Yeah, I'm probably flailing at windmills, but I do dislike how we
often end up just growing the very core headers that get included by
everybody without ever trying to fix that uncontrolled growth..
