Bouncing this to the list.

You wouldn't happen to know the reason by any chance?

With the proper changes (still assessing them) that should work on OS X too, no? With the USE_KPROCESS_FOR_KIOSLAVES/QProcess::start I had to jump to a number of hoops and resort to calling the commandline AppleScript interpreter (osascript) to ensure that the launched process is started in front of the calling process. Not easy, as AppleScript isn't really designed for this so I also had to subclass QProcess to launch osascript in detached fashion and set a kill timer to get rid of it should it not complete within a reasonable time. Since kinit will use ObjC++ in my proposed patch it should be possible to achieve the same thing (process opens in front) directly using an appropriate API (AppKit).

I'll queue testing this on my todolist.
