I don't think we open enough config files for it to make much difference 
(although I may be wrong when it comes to cold starts and machines with 
little memory), I think, since the commonly used files will probably be in 
the caches since after the desktop startup anyway; particularly since KConfig 
parser and I/O code are very fast, while the data-structures are slow 
(Maintaining a red-black tree with a key containing two strings is a lot more 
expensive than one would expect). Plus, you have to do IPC, which even when 
hyperoptimized may still take some context switches.
