Overview

Concurrent::Event with an iteration counter so callers can detect that the event was reset (e.g. a new navigation started) while they were waiting on it. Mirrors ferrum’s Utils::Event.

The base Concurrent::Event allows wait/set/reset cycles, but a wait that returns true after a reset → set is indistinguishable from one that returned true on the original set. The iteration counter, bumped on every reset, lets callers compare before and after to tell whether the event was raced by a reset.
