I think this limit is great. It limits the cashed
data to about 540000 words.

K, L = 3+1, 3+20 ; print reduce(lambda x,y:x+y, range(K, L+1))*2000

This makes me think of integers which are cashed as well.
After some big range expressions, we have thousands of thousands
of integer slots available, eating memory.

In this case, things are more difficult, since integers are
alloted in pages. Not so bad, but we might end up
with many many pages where only a few ints are used.

Any ideas how to limit this acache as well?
