byte-compile-noruntime-functions

[Glenn Morris <rgm@gnu.org>]

I want to apply the following patch to bytecomp.el, but I've noticed
some things about byte-compile-noruntime-functions that I don't
understand.

1) It's a global variable. It's not buffer-local, nor does it get
   reset like byte-compile-unresolved-functions does (in
   byte-compile-from-buffer).

2) Nothing else ever seems to remove items from it, so it just grows
   and grows in any Emacs session.

Do these facts make sense?
