 Hello,

 just in case nobody has noticed yet (which is presumably the case :) ), 
kdeinit in KDE4 has always been not much more than a pretty complex way to 
say execve(), due to at least 4 independent changes somewhere. Since kdeinit 
still makes some difference (about 0.7M per process on 32bit with my debug 
build, I have no idea what the status is with final builds with symbol 
visibility), and it's also suitable for hacks working around lameness of 
others when it comes to handling memory usage, I've made it work again.

 Non-ELF platforms: The KDE4 build system no longer creates the extra modules 
like KDE3 did in lib/kde3, there's only lib/libkdeinit4_whatever.so, and I 
took the liberty to not play with cmake and just dlopen this one directly. 
IIRC the KDE3 setup was done for platforms that couldn't dlopen libraries, in 
case this still matters, feel free to adjust r967207 and duke it out with 
whoever changed it in the buildsystem.

 I also changed kdeinit to now load libplasma during workspace startup, 
instead of libkonq (which doesn't seem to be used that much nowadays). 
Currently libplasma is pulled in by a lot of stuff in workspace anyway 
(plasma, krunner, ksmserver, kwin, kded via khotkeys via libworkspace) and it 
has somewhat heavy dependencies. Especially if you happen to have nvidia's 
libGL, which is 11M per process and I promised Thiago that we can do 
something about it. I thereby claim the achievement of reducing KDE's memory 
usage for just the plain desktop by about 33M (which itself was enough to fit 
whole plain KDE3), feel free to beat that ;).
