Hi. I've been talking with a computer science professor at my
university about Mac OS X and he asked me if the kernel was single

what he's talking about. =) Thanks.
There's some confusion here, I think.
The 'single-' vs. 'multi-' server issue arises because of the fact that
Mac OS X uses Mach in its underpinnings (the Darwin OS). However,
unlike the more 'academic' uses of Mach (ignoring OS/1), Mac OS X does
not have a server-based OS. The Mach implementation is tightly
integrated with the rest of the (BSD-based) OS, and there is no attempt
to run operating systems as "server processes".
Although Darwin/Mac OS X uses Mach 3.x, it is implemented in a way that
is closer to Mach 2.x. That may help discuss this with your prof.

Justin
