This & 5/9 would I think be better squashed into their respective "main"
patches.

I presume you mean the "main" patch for this one is 8/9.  I was trying
to find a way to break up that large patch, but this is pretty small
so...sure I'll squash it in.

What are you referring to as the "main" patch for 5/9, though?  It
only seems related to 6/9 and 7/9 to me, but I very deliberately split
those patches off and don't want to confuse them with unrelated
changes.  I disagree with combining 5/9 with either of those.

I just gave it a quick initial skim.

I have sometimes found it a bit harder to review your patches due to
over-splitting.

E.g. (went back and looked) here tmp_objdir_discard_objects() is
introduced in 1/9 but used in 8/9. "path_messages" is then introduced in
5/9 and used in 8/9, no?

Anyway, just a bit of feedback. FWIW not just bikeshedding. I do find
myself stopping at 1/9, paging to 2/9, searching for the function, not
there, checking 3/9 etc.

I realize this is a bit of a stones & glass houses comment, but I find
it a bit easier to review things when a patch is larger v.s. having it
split up in a way where preceding steps don't do anything yet except
wait for use by a subsequent patch.

0.02 etc.
