I think Linus' just asked for some working "real world, not micro" code that
demonstrates use.
A prototype type implementation of the glibc malloc cache using this may
be good enough.
Even if the API still changes slightly later in review I would assume
the basic concepts will stay the same, so it would be likely not
too difficult to convert that prototype to the later final API.
