commit 7d4ada66c96a748ce92f8e8edac149361c3dc829
Author: Behdad Esfahbod <behdad at behdad.org>

    Mark unsed members with a "Z" suffix
    
    There may be more.  There are members that are by definition
    redundant or reserved and not needed, NOT what we *currently*
    don't use.
    
    I'm sure there's more...
