Thanks for looking at it, but now I think it is something weird with Claws output. When I look at the entry for the pid in /proc, the name is different in different places. In /proc/$pid/cmdline, it is correctly shown as 'claws'. But in /proc/$pid/status, it shows it's Name as 3. So I think it is a problem with Sylpheed-Claw's way of reporting iteslf? Every other process seems to have Name and cmdline as the same (or similar).
