I'm curious! If you are trying to cancel an async, why was it invoked in the first place? Or is this for operations no longer requested, like a big upload or something?

Inhibitory neurons make it possible for you to walk down stairs without falling the whole way, so whatever trickster is voting down neurons, cut it out

People and programs change their minds all the time. A lot of behaviors we consider intuitive rely on some form of cancelation.

People gave a few examples in this subtopic: https://news.ycombinator.com/item?id=14962684

Perfect! Thank you.
