> write_all() and wait_until_sent() take the timeout as a raw Jiffies,

> Take the timeout as Delta<Jiffy> instead.

> The C side treats a timeout of 0 as "wait indefinitely". The Rust API
> does not keep that meaning. A timeout of 0 or negative is rounded up
> to one jiffy. A caller that wants to wait indefinitely passes
> Delta::from_jiffies(isize::MAX). That value is MAX_SCHEDULE_TIMEOUT.
> The C side replaces 0 with MAX_SCHEDULE_TIMEOUT before it waits, so
> this gives the same wait as a timeout of 0 did before.
