I am using whatever method ftplib uses by default, in other words, I
do not explicitly set the socket as blocking or non-blocking. 

After reading your reply (and the other I received), I tried
explicitly calling setblocking(1) on both the FTP socket (ftp.sock)
and the socket that is returned when I call transfercmd. However, the
PORT call's response still comes after the STOR command. (As far as I
could tell, setting blocking mode seemed to do nothing.)

It does always happen at the beginning, even when uploading to
different servers. But since I cannot get it to upload more than the
first file, I do not know if it would happen at other points in the
upload. 

Thanks for your help!
