1) Where can I download the kernel so I can look through some of the
source myself? It's not on the list at macosforge.org.
2) More description of NPROC, MAXUSERS, and "scales", and UNIX03 would
be helpful. I'd be happy to read up on them if someone could point me
in the right direction. Where should I look? The source code?
3) Does anyone know what buttons I could push at Apple to get (at
least) the server kernel compiled with "larger scale" or something
like that? I'd like this fix to be available to the larger community,
which really means getting it into an official OS update.
