BTW: It looks like your patch has a dependency on the 17-patch dev cleanup set from
David, [and now on the header include bug fix I submitted yesterday too], so
you should probably note that in any future revs of the patch you do. Save
some head-scratching from those of us testing it out. :-)

Thanks,
