kdeinit exists to 'preload' all libs. It was introduced, to keep the loading 
time of apps down to a bearable time. Without kdeinit or prelink, the startup 
time of every kde app would be insane. That is, why a single app should not 
be so much affected like the overall kde startup time. After the start, 
everything is 'prelinked' (not really, but kdeinit will be running), and the 
times of the apps are depend on how fast they 'link' against kdeinit....
