I.e. in other than "delay for missed ticks mode". Would have been
nice if you had spelled this out explicitly. With that the question
then is - should the field perhaps be used when non-zero, and the
function only be called otherwise?

Wei - regardless of the answer to the above (i.e. regardless of
whether a v2 is going to be needed) I think we want this in 4.6.
