Well I'll be.  Someone is running a multi-user Unix system.  That's 
something I've always wanted to do or find someone doing.

I can't yet tell if that's six logical CPUs or more.  x86_64 cores 
/could/ have hyper-threading et al. and more logical CPUs.

But still, six contemporary CPUs could be a lot of computing power.

16 GB of memory is nothing to sneeze at, especially for running commands 
in a CLI environment.  --  I'm assuming no daemons saying FEED ME RAM.

I applied for membership.  I'll be interested to see if I'm granted 
logon permission.  :-)

Thank you for sharing Dan.
