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?
