This class supports the makefile() method on sockets. It provides
the raw I/O interface on top of a socket object.

the number of bytes read. If the socket is non-blocking and no bytes
are available, None is returned.
If *b* is non-empty, a 0 return value indicates that the connection
was shutdown at the other end.
