I'd say that namesys is using UML (user-mode-linux.sf.net) to develop 
raiser4 (smart guys, uml rocks).

These are probably left overs from UML's SKAS-host patch. If I'm correct 
you may try to reverse the SKAS patch from that tree (the patch is 
located at UML's site). It won't do any harm, anyway...

Regards,
Nuno Silva
