Bug 355182

When haven ksysguard open for longer, some processes do no "go away", they stay in the list although the are long gone. Closing and reopening updates the list properly.

Reproducible: Always

Steps to Reproduce:
1. Create a script that runs a program multiple times (like let inkscape convert images in a batch script)
2. open ksysguard and let it open for ten minutes
3.

Actual Results:  
Multiple inkscape processes are shown with some cpu usage

Expected Results:  
Only one (or two) inkscape processes should be shown (or none, if the script is finished)

Right now I also have a kate process showing up in the list with 27k/s that is long gone really...
