Detailed Description

Suspends a FreeRoutine until a caller-supplied predicate returns true.

await_ready() evaluates the condition immediately; if already true the coroutine does not suspend. Otherwise await_suspend() arms the promise so the scheduler's CONDITIONAL thread will evaluate the condition on each pass and resume the handle when it returns true.

The condition is moved into the promise on suspension and cleared on resumption. It must be safe to call from the scheduler thread.

auto routine = [&]() -> Vruta::FreeRoutine {
    while (true) {
        co_await ConditionAwaiter{ [&]{ return flag.load(); } };
        do_work();
    }
};
