    Just to be clear _these_ patches do not change the existing ABI.

    They do add a new ABI: the end_phys_index file. But, it is completely
    redundant at the moment. It could be taken out of these patches.

    That said, fixing the directory creation speed is probably a worthwhile
    endeavor too.
