François Laignel 61c62ee1e8 ts/timers: multiple improvements ... This commit improves threadshare timers predictability by better making use of current time slice. Added a dedicate timer BTreeMap for after timers (those that are guaranteed to fire no sooner than the expected instant) so as to avoid previous workaround which added half the max throttling duration. These timers can now be checked against the reactor processing instant. Oneshot timers only need to be polled as `Future`s when intervals are `Stream`s. This also reduces the size for oneshot timers and make user call `next` on intervals. Intervals can also implement `FusedStream`, which can help when used in features such as `select!`. Also drop the `time` module, which was kepts for compatibility when the `executor` was migrated from tokio based to smol-like.		2022-09-13 07:29:50 +00:00
