At work, where I still use Windows, I still have Emacs 20.7, so I
don't know how much that will help.

Right, I think what was missing was spliting between lines.  When
people sent their entire buffer and every line of the buffer was
"short", then this would trigger the deadlock.

Not on my GNU/Linux system with the following script used as the bogus

#! /bin/bash
read -p "SQL> "
while true; do
    LINE=$(($LINE + 1))
    case $REPLY in
            echo "foo!"
            read -p "SQL> "
            read -p "  $LINE: "

I will try and remember to run the appropriate test when I install
Emacs 21 on a Windows machine.
