I started to try the strace suggestion, and to
simplify things, I logged in as root, rather than
user followed by su - . To my surprise, the
problem disappeared. Therefore, to demonstrate
the problem:
1. log in as user (not root)
2. (in my case) startx
3. pop a Shell Konsole
4 su -
5. tail -f /var/log/<some log file you can send to>
6. click the x to kill the Konsole
7. pop another Shell Konsole
8. su -
9. ps -ef | grep tail
10. I find that the tail process persists
But not if the original login is root. I wonder if anyone
else can reproduce this.
I hear from above that it is now bedtime at -0500, so I'll
try the strace tomorrow. Thanks for your interest.
Mike.
