Absolute scheduling?

I know that to do this kind of thing "properly", you need a bunch of other stuff.

To be honest, I'm just hoping to have some stuff added so that I don't need to run both `schedule` and [`sched`](https://docs.python.org/3/library/sched.html) in the same process.

This would be really handy for in-memory objects or other resources that are tied to process lifecycle. (My specific use case is remote access credentials that expire. I get the timestamp of exactly when they expire, and I don't care if the process restarts because I just reauthenticate at start.)
