    A selector supports registering file objects to be monitored
    for specific I/O events.

    A file object is a file descriptor or any object with a
    `fileno()` method. An arbitrary object can be attached to the
    file object which can be used for example to store context info,
    a callback, etc.

    A selector can use various implementations (select(), poll(), epoll(),
    and kqueue()) depending on the platform. The 'DefaultSelector' class uses
    the most efficient implementation for the current platform.

        This wraps _fileobj_to_fd() to do an exhaustive
        search in case the object is invalid but we still
        have it in our map. Used by unregister() so we can
        unregister an object that was previously registered
        even if it is closed. It is also used by _SelectorMapping
