Makes sense.
I need a couple of adjustments before it compiles on Windows:

When applied on top of current `master`, I need to replace the &c_tree by
c_tree.hash.

... &index_tree -> index_tree.hash.
These are probably changed to use object_id's already in `pu`, I guess.
I also need this change:

Since `pid_t` is `unsigned long long` on Windows, I changed the %d" to
%"PRIuMAX and cast `pid` to `(uintmax_t)`.
With those changes, the entire patch series compiles here.
BTW t3903 runs in 13m30s here with this patch series, 14m30s otherwise.
That might not seem like much, until you realize that t3903 *still*
performs a metric ton of Unix shell scripting outside of `git stash` (and
that is the reason for the slowness).
Ciao,
