On the slowest machine that I have access to, a 500MHz P3 the
xterm.elc load time (as reported by elp) goes from 2.2 seconds to 0.3
seconds if all the substitute-key-definition calls are moved before
(let ((map (make-sparse-keymap))) 

Stefan, do you have any idea what might be the problem here? (You are 
the last person to have done changes to substitute-key-definition, so
I hoped you might understand what is it doing, because I don't). 
Could you please take a look? 

The "let" at the beginning of xterm.el does this: 
  (set-keymap-parent map (keymap-parent function-key-map))
  (set-keymap-parent function-key-map map))

Does substitute-key-definition have a problem because of the way
function-key-map is modified above?
