Timing. I've been preparing a patch that provides
`clear_unpack_trees_porcelain()` and fixes all such leaks. (About 10% of
all the leaks that are reported when I run the test-suite!) My patch
conflicts with this series for obvious reasons. Figuring out the
conflict resolution might be non-trivial, and I suspect it would even be
an evil merge. I'll be holding off on that patch until this has landed.

BTW: s/also data/also free data/. But since I'm promising to get rid of
this TODO quite soon after this is merged... ;-)
