I have reported a problem with ioctl(TIOCGWINSZ) in the kernel a few weeks
ago to the list as well as to Linus. He asked me to try and pin-point it
to the specific kernel. I sent my response to him and to the list a
couple of times but received no feedback.

What I responded with is as follows:

======= cut here =======
Okay, it is definitely 2.0.30 that is at fault. This is easily producable
on my system from tty1 virtual console:

1. login as gomer
2. rlogin -l gomer localhost
3. stty size
4. if size == ok, type "exit" and goto step 2
5. stty size -> 0, 0

While doing this, I also noticed something else. After doing an "exit"
and redoing rlogin -l gomer localhost, there is a very noticable delay of
4-5 seconds taken to actually login (this is on a totally idle PPro 200).
The very first rlogin is RAPID. The second rlogin is always delayed.

When I went to 2.0.29, rlogin was consistantly rapid *always*. And after
20 or more attempts at reproducing the incorrect row/cols stty values, I
gave up.

======= cut here =======
I have since tried the above with the pre 2.0.31-2 patches applied. The
same problems still occur so I guess I will be stuck with 2.0.29 again.

In addition to attempting to strace where rlogin was "pausing" temporarily
(see above), it appears to be on a connect(127.0.0.1) sometimes (but not
always) and on read() of /etc/motd. Again, with 2.0.29, things are very
rapid under all circumstances.
