I've been tracing this bug tonight, and I feel concerned about it. The

Good question. The seek must be in the binary write. I'm not calling it
directly. Again, the error only occurs when the binary flag is set. Any
write on a socket file with the binary flag set causes a seek

The problem only occurs with the binary mode set, which is very strange.
The following:
file = s.makefile('w',
I found a problem with the fepy socket module. Seek operations aren't
supported, but they are supported in CPython (not totally sure how they do
that).
Here's an example.
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("baus.net", 80))
file = s.makefile('wb', 1500)
