## [Unreleased]
### Added
- `half_period_counter` containing utilities for implementing a half-period-counter based monotonic.
- `should_dequeue_check` to the `Monotonic` trait to handle bugged timers.
### Changed
### Fixed
- **Soundness fix:** `TimerQueue` did not wait long enough in `Duration` based delays. Fixing this sadly required adding a `const TICK_PERIOD` to the `Monotonic` trait, which requires updating all existing implementations.
- If the queue was non-empty and a new instant was added that was earlier than `head`, then the queue would no pend the monotonic handler. This would cause the new `head` to be dequeued at the wrong time.
