This bug has been annoying me for months.  I have been doing some further
investigation over the last couple of days, including tracing the hang,
which I have just added as an attachment.

All my testing has been done using 3.4p1 running on AIX 4.3.3 ML08 (and ML09).
OpenSSH_3.4p1, SSH protocols 1.5/2.0, OpenSSL 0x0090600f.

Output generation command:

perl -e 'while(1){print"O","X"x78}'

This command hangs in under 2 seconds for me.

Test results
------------
(openssh means the above version, ssh2 means ssh.com v3.1.2 CLIENT)

rlogin testserver  -> openssh localhost -> generate output -> HANG
telnet testserver  -> openssh localhost -> generate output -> HANG
openssh testserver -> generate output   -> okay
openssh testserver -> openssh localhost -> generate output -> okay
rlogin testserver  -> ssh2 localhost    -> generate output -> okay
