When my partner does this to me I call it his "audio buffering" mode -- he'll be absorbed in something and make no indication that he's heard me, but if I wait long enough (in the 15-60 second range), it'll suddenly make it all the way to his conscious attention and he'll respond as though there was no gap at all.
