I have HP/UX 11.00 installed on my machines at work, and I recently
began deploying OpenSSH to them.  I compiled it on our Development
machine, and deployed it via tar/ftp to other machines.

Our Devel machine does not exhibit the hang.  However, our secondary
development machine DOES exhibit the hang.  Both of them have the
same OS and patch-level as far as I can tell.  Here's the debug
output for the close of the sessions.

FROM C3P0 TO DEVEL -- NO HANG:

That's what I have...  Any suggestions?
