man, was I on the wrong track.  turns out the problem was that I was 
uploading a Excel file and something in there was getting thought of as 
an end-of-file marker.  To fix:

import msvcrt
msvcrt.setmode(0, os.O_BINARY) # stdin = 0
msvcrt.setmode(1, os.O_BINARY) # stdout = 1

(credit where it's due:  I found this on ASPN.)
