I guess when I think about it, they aren't extremely time critical.

It happens...more often than not.
You hear 'I need sub-nanosecond accuracy to time my slot cars!'...come on...do you really?

My main worry was about missing interrupt events. But I guess as long as the interrupt does trigger - say a millisecond late, that shouldn't impact the performance.

Well if I knew what the trigger and the items involved were, I might have a better idea laying in the back of my head on how to compensate...
