  Target Milestone: ---

I am having lots of proplems with KDE and dolphin freezes lately. It didnt
result in a crash, but Dolphin search making the complete KDE shell
unresponsive, specifically the panel and meta keyboard shortcut. Alt+Tab works
though.

I just searched for "benchmark" in a folder with some symlinks and moderately
many files.

Apps should never cause the entire shell to hang? Is there a Memory allocation
problem, or CPU power? 

KDE shell should have higher privileges so that it never just hangs, but the
app is throttled, if that is possible.
