As others mentioned, please post the bug to the tracker. Also, please
assign the patch to me ("jackdied") and mention the previous bug
number - I thought I had reviewed all the telnetlib bugs including
those that were closed WONTFIX.
Thanks for the kick in the pants, I have a whole new inner loop for
data processing but I haven't applied it. I've been adding unit tests
to the module so I could be sure I wouldn't break anything but never
finished the job.
