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.
