easier to read, but since no one else seems to think so, closing.

Before c13baa10d55ec863d3ceaea48c6b2959ece98198, `package-initialize'
takes ~100 ms on my machine, with 92 packages.

After this revision, it takes ~7.7 seconds.

Provided there's no obvious low-hanging fruit for performance
improvement, we should at least avoid exercising the new logic when
Emacs is just launching. There's simply nothing to reload yet.
