You're still using arguments -against- putting software in the kernel. 
You don't decrease software's chances of "being broken" by putting it in 
the kernel, the opposite occurs -- you increase the likelihood of making 
the entire system unstable.  This is one point that Solaris and Win32 
have both missed :)
