Hi folks.  For a project I've been doing for some time now, I need to keep
some state info in the Class of a given object.  I'm annoyed by the fact
that I can't add instance variables to a Class object, and have to "simulate"
them with static variables.  Off the top of my head, I don't understand this
restriction.  Can someone out there convince me that this is a necessary 
and proper restriction?

For those who care, the situation for where I need them is that I have a set
of classes which, at run-time, start up companion processes on other machines.
The machines that could run a given class are queried when the class is
+initialize'ed, and then when an instance of that class is requested, that
list is queried to find the best host at that time to run the new instance
on.  I need to keep this list of possibleHosts somewhere, and it seems 
appropriate to make it a class instance variable, but as far as I can tell,
there's now way in ObjC to do this.  Pleae correct me if I'm wrong...
