    // before "park" causes "park" to return immediately): it *seems* like alertable sleeps paired
    // with `NtAlertThread` do actually do this too, but there could be some caveat (e.g. it might
    // fail under some specific condition), whereas `NtWaitForAlertByThreadId` must reliably trigger
    // this behavior because `RtlWaitOnAddress` relies on it.
