Comment 54 for bug 1502556

@ycollet
I believe that the problem that you have described is different from the one being discussed here. I think it will be good to create a separate bug report for the cpu load issue. Nevertheless, I have experienced the CPU rise issue in similar circumstances. It seems that whenever you put a frequently updated plasmoid either in the system tray or on the desktop, the cpu spikes.
In my case, whenever my plasma-nm or the notification icon are showing the spinner (the semi-circular stuff that spins around the a pertinent icon in the system tray to indicate that work is being done) for loading a connection or displaying the status of a copy job that takes a while to complete, my CPU usage goes wild, and I know that it is not caused by the connection or the copy job (i.e. the same copy on cli shows no issues.)

Okay so the point of this comment was to move the CPU issue into another bug :). Sorry to divert from the discussion of this memory leak problem.
