(a commentary regarding the "logistic review" of this patch)

we discussed yesterday quickly on #xorg-devel (IRC) and seems there's no one
maintaining or even giving some real love to Xephyr - Julien was the last one
that put some effort (trying to convert the communication of Xephyr with the
host server using XCB instead X11), but even him doesn't have time to jump
over and review your patch.

This all means, that we need someone to take care of such component and do the
proper maintenance. So, if you don't have yet, I'd encourage you to get a
freedesktop account and go ahead pushing your changes to Xephyr repository
(eventually you'll might need to coordinate with the RM also - Keith):

Thank you for the effort.
