I don't know much about tq.el, but I'm leery of the line

(tq-queue-add tq (and delay-question question) regexp closure fn)

-- it seems to me that you want to include 'question' if and only if you
aren't already sending it (because tq-queue-pop will definitely send it if
you include it).  So shouldn't it be (unless sendp question) rather than
(and delay-question question)?
