Oh no!  It's not gone, but just doesn't occur anymore as often as it did
before...  I'll analyze Git's ``git checkout'' source code.

I've never seen any inconsistencies using and repeating these commands:

    $ rm -rf ar_master*
    $ (cd git/ && git archive master) | (mkdir ar_master && cd ar_master/ && 
tar -x)
    $ diff -x .git -ru tar_master/ ar_master/

Or:

    $ (cd git/ && git archive master) | md5sum

Thus, the ``upper layers'' of Git seem to be fine.

This really didn't show up anymore -- so far...
