Since mlocking this amount of memory will require root privileges, this 
can only work on a full KDE session, in which we can run a setuid root 
process to do the operation.

This means we won't have the issue if other desktops start doing it and 
you just happen to run one app from it.

But it will be a problem if you have more than one desktop running on the 
same machine.
