We're getting occasional reports of PuTTY sessions dying with
messages like "Server sent disconnect message: received data for
nonexistent channel -1". Reports so far:
OpenSSH-1.2.3 on Debian potato, 0.52 on W2K, port forwarding "mapping
port 993 to 3993" (don't know which way)
"Server sent disconnect message: received data for nonexistent
"SSH-1.99-OpenSSH_2.9.9p2", 2002-03-14 on XP Pro
"Server sent disconnect message. Received ieof for nonexistent channel -1"
We believed this fixed as of 2002 May 18 (and have had one person
report that our fix made their problem go away), but we've received
reports that the `ieof' variant at least is still out there (in
2002-07-04 and 2002-09-07).

We believe the last bug of this kind has been squashed as of 2002-09-16;
no-one's confirmed this, but no-one's complained either. We've also put
code in which will hopefully make catching any remaining problems
