:As long as there are no other comments besides you and me, just speedy-close it with "speedy keep/administrative withdrawal due to ongoing RfD" with a note that you plan on relisting it on some future date, then remove the AfD template.  Also put the old-afd templates on the talk page.  Once someone else comments you'll want to get that person's consent before speedy-closing it.  The WP:AfD page and related page show how to speedy-close an AfD. ///(e-mail)
