///
/// Unlike [`EventLoop::run`], this function accepts non-`'static` (i.e. non-`move`) closures
/// and returns control flow to the caller when `control_flow` is set to [`ControlFlow::Exit`].
///
/// # Caveats
///
/// Despite its appearance at first glance, this is *not* a perfect replacement for
/// `poll_events`. For example, this function will not return on Windows or macOS while a
/// window is getting resized, resulting in all application logic outside of the
/// `event_handler` closure not running until the resize operation ends. Other OS operations
/// may also result in such freezes. This behavior is caused by fundamental limitations in the
/// underlying OS APIs, which cannot be hidden by `winit` without severe stability repercussions.
///
/// You are strongly encouraged to use `run`, unless the use of this is absolutely necessary.
///
/// ## Platform-specific
///
/// - **X11 / Wayland:** This function returns `1` upon disconnection from
/// the display server.
