ok i'm just a curious non-techincal newbie, but does darwin/ppc run the 
kernel concurrently on multiple processors? does any 'nix? if so, what 
is an example of two tasks the kernel could be doing concurrently? are 
these foolish and simple questions? do you consider the kernel to be 
strictly that which is not a process (below ALL processes) or do you 
consider low-level processes like init and the vm pager and the like to 
be part of the "kernel code"? if other 'nix OSes can run kernel code on 
multiple processors concurrently what holds netbsd back?
