Just want to mention that this patch breaks older versions of valgrind 
(including the current release)
https://bugs.kde.org/show_bug.cgi?id=357833
It is fixed in trunk (and even triggered some good cleanups, so the valgrind
developers do NOT want it to get reverted). Rawhide already has the valgrind
fix, others might not, so if we consider this for stable, things might break
here and there, but in general this looks like a good cleanup.
