I should have written that we "unpack (or better turn loose) the 
promisor objects" not the `blob` objects. Instead, I should have
written something like:

    ... ends up loosening all promisor objects, on this case all
    the `trees` and `commits` objects, into the filesystem ...

Apologise for the confusion and this misleading message. I'll clarify
this in the v2.
