For those of you willing to build out of XFree86's CVS, a new tool
that will get you resource usage out of the X server.  We should have
done this in 1988.  Sigh...

Status:   
   I've commited a new extension to CVS.  It's called "X-Resource"
and it lets you query how many clients are currently running and
how many of each type of resource they have.

   I've attached a simple client.
