Function run_with_timeout 

pub fn run_with_timeout<T, F>(timeout: Duration, f: F) -> Result<T, TimedOut>
where
    F: FnOnce() -> T + Send + 'static,
    T: Send + 'static,

Runs f on a helper thread and waits up to timeout for it to finish. Use this to bound any blocking call (std::fs::*, image::open, a subprocess .wait()) that could otherwise block indefinitely against an unresponsive mount point.
