Here's a script, that will also detect termination (it works with ksh
and zsh, but not with dash and bash, which seem to have broken signal
handling):
------------------------------------------------------------------------
#!/bin/ksh
n=${1:-200}
n=$((n+0))
c=0
trap 'c=$((c+1))' CHLD
for i in `seq $n`; do xterm -geometry 80x24+$((2*i))+$((2*i)) -e true & done
while [ $c != $n ]; do sleep 1; done
------------------------------------------------------------------------
This can also trigger the bug with the default fvwm configuration
in Debian, but less often than mine. So, you may need to run this
script several times.
