Actually - this seems to work for me just fine...
Don't know why, because I know that statement in the Emacs Lisp manual  
as well.

Ah, maybe there are different Emacs versions in play? 23.1.90.1 is the  
one I jut now tried.  It does not work in Emacs 22.

I would like to still support Emacs 22, so I think we should change  
how the hash is written out, my using maphash to draw out the key/ 
value pairs when writing, and puthash to build the cache when reading.
