Note that I'm less and less sure that this caching is still important.
I have turned it off here (or rather I have changed the code to always
refresh the cache) and it's not noticeably slower (on my 266Mhz PII).

The worst case is with X-Symbol which has an enormous keymap (because
of two input methods implemented as keymaps: one in a menu and another
bound to C-=) where the menu takes about 1s to come up.
