John McCall	8ac4362754	Implement a simple library for task cancellation and status management. ... There are things about this that I'm far from sold on. In particular, I'm concerned that in order to implement escalation correctly, we're going to have to add a status record for the fact that the task is being executed, which means we're going to have to potentially wait to acquire the status lock; overall, that means making an extra runtime function call and doing some atomics whenever we resume or suspend a task, which is an uncomfortable amount of overhead. The testing here is pretty grossly inadequate, but I wanted to lay down the groundwork here.	2020-10-15 00:36:36 -04:00
