I'm trying now, and it did appear to get rid of the zombies.
Here's a quick test.
set -e
for a in `seq 1000`
do
echo -n "$a "
xterm -e ssh nonexisting
done
echo ""
(The idea here is that 'ssh nonexisting' should do some work and then exit,
"xterm -e false", etc. don't appear to trigger the bug.)
Prior to the patch, one of the xterms would hang after the counter reaches a
random (reasonably small) number.
After the patch the script runs till completion.
Cheers
Michiel
