Whilst I can appreciate the value of adding the nextPollTick reset as a way of getting soon-as-possible response from the plain old checkForInterrups code, I feel sure there was a more sophisticated technique that was discussed many (many, many) moons ago. August '00 or thereabouts seems to be when most of the email flopped around.
Trouble is I can't spot an actual email with any sensible seeming details in it, so maybe it was something discussed in person or by phone. Does anyone else recall a possible technique from back then?
