    True.  A command-line option would also be in order, to save the delay at
    startup before the lisp variable is eval'd.  Anyone feel like adding these
    (cmd line opt & lisp var)?  

If the caching works reliably and if it does not cause problems
when the color map is full, there may be no need ever to turn it off.
Or just having a C variable that you can set with GDB could be enough
for debugging purposes.
