That looks awfully like a wrapper for a socket to me. All of those
system calls are peculiar to sockets.

There doesn't necessarily have to be a wrapper class for each kind
of file descriptor. There could be one I/O class that handles everything,
or there could just be a collection of functions.

The point is that, with a completion-based model, you need a function
or method for every possible system call that you might want to perform
