Interesting that you should point this out.
My throttle is only valid for intervals, which fire repeatedly.
There are no restrictions on timers, which fire only once.
So if a timer is scheduled for now + 10ms, then it fires at now + 10ms.
However, if that timer schedules another timer for now + 10 ms, then that timer fires in 10 ms, and it continues every 10 ms, and you have found a way around my restriction.
In any browser, that's more resource intensive than a 10 ms interval.
We're constantly creating objects every 10 ms, which gc must clean up before they accumulate, etc.
It's so inefficient I'm guessing nobody would do this, except maybe an acid test.
