[Async-sig] Blog post: Timeouts and cancellation for humans

[Dima Tisnek]

Very nice read, Nathaniel.

The post left me wondering how cancel tokens interact or should
logically interact with async composition, for example:

with move_on_after(10):
    await someio.gather(a(), b(), c())

or

with move_on_after(10):
    await someio.first/race(a(), b(), c())

or

dataset = someio.Future(large_download(), move_on_after=9999)

task a:
    with move_on_after(10):
        use((await dataset)["a"])

task b:
    with move_on_after(10):
        use((await dataset)["b"])
