You are right processes are beeing swapped out, but since I did not start any new 
processes during my tests (except for digikam itself) the swap space should only 
grow when digikam is started for the first time. However I can repeat this behaviour. So if I 
terminate digikam then start it again and look at the very same photos then 
terminate digikam and start it again etc... then swap space usage is increasing 
with each try. This is not normal. Here is a sequence of free calls after I terminated 
digikam. After the free call I restarted it and looked at the very same photos again. 
All in all I did this 10 times (see numbers I added). And after the 10th try the system used 1.4GB swap whereas 
it had no swap usage initially. Below you can see how swap  usage is increasing 
each time I restarted digikam and looked at the photos:

Next I terminated my KDE session and kdm as well and restarted it and logged in again. 
The swap space was still used. This should not happen as I think.  
Am I the only one having this behaviour?

Thanks
