I am assuming you are going through the software loopback driver. Well,
on one of our machines (this one was also running 4.2 based networking
code at the time) I got:
ftp> bin
        200 Type set to I.

ftp> get xxx /dev/null
        200 PORT command okay.
        150 Opening data connection for xxx (127.0.0.1,1028) (17444448 bytes).
        226 Transfer complete.
        17444448 bytes received in 1.34 seconds (12673.608 Kbytes/s)

The numbers are better with our newer 4.3BSD based code.

So I guess the answer to your question is yes.
