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 information, a callback, etc. A selector can use various implementations (select(), poll(), epoll()...) depending on the platform. The default `Selector` class uses the most efficient implementation on the current platform. NcCs t‚dS)a3Register a file object.
