As far as backwards compatability, it could cause things to be called more
sooner than desired. eg a task that registers for every 30 seconds but takes 5
seconds to complete would be called after 25 seconds, instead of the expected
(based on current behavior) 30.

I've no objections to such a mode, but I'd say it should be an option
(defaulting to the current behavior, for now).

<nitpick>well, it wouldn't elminate it, but it would greatly reduce
it.</nitpick>

You are lost in a twisty maze of little standards, all different.
