I started heating my sparge water much later than I should have, so there was a half an hour after mashing out (single infusion mash) before I batch sparged. Is this one of those RDWHAHB things? 

Stop worrying and have a homebrew.
(thinking, thinking, who said that???).
You can sparge with cold water next time with virtually no difference in the amount of sugar extracted and only a minimal extra time to bring the wort to a boil. With batch sparging you don't even need a mash out, just drain the first runnings, dump in the sparge water, stir well, and drain again.
