An object abstracting over a file.
Implementation of an IPv4 TCP socket.
A timer is an object whose file descriptor is added
to epoll, used to maintain the mapping between the file descriptor
and the callback, at the minimum. Other fields can be used for
further synchronization and bookkeeping matters.
