Yikes.  SS1ks are nice but I'm not sure they are cost effective.  I 
certainly can't afford an AS2100.

Yikes.  Sounds hard.  Maybe I should just give up on having decent performance
and just go get a second job instead so that some year I'll be able to just

I've been running Linux a long time.  I have a few gripes.  I definately
