This API offers somewhat more flexibility than
L{twisted.internet.interfaces.IReactorSSL}; for example, a L{TLSMemoryBIOProtocol}
instance can use another instance of L{TLSMemoryBIOProtocol} as its transport,
yielding TLS over TLS - useful to implement onion routing.  It can also be used
to run TLS over unusual transports, such as UNIX sockets and stdio.
