On a slow filesystem it gets more noticeable, but I have been
wondering (without a debugger or a profiler, as I am supposed to be
on vacation) for the past few weeks why these two commands in the
same repository perform very differently:

    $ git write-tree
    $ git commit -q -m msg

Especially even after running the former, running the latter, which
I naïvely thought that it only needs to create a commit object with
"msg" and wrapping the result of the former (which is more-or-less
instant) into it, and do nothing else.
