During my KDE session there are kded4 zombies, which accumulate over time. Reproducible: Always Steps to Reproduce: Login to the KDE desktop and use it for some time. I logged in on Sunday (less than a week ago) and already have 14 zombies in my process list. I have not checked (yet) if this is related to sleep/wakeup cycles on my notebook. Expected Results: The master kded4 process which forks the workers needs to wait() on its child processes to cleanup after they finished.
