Perhaps I think too much like a programmer instead of a user: I simply
enlarge those values when I need them bigger, then recompile. The
version in teTeX and TL2005 still has this (2^18-1) limit, ConTeXt
simply does not reach it yet.

For TL2006, the plan is to make all upper limits equal to their
theoretical size (for trie_size, i believe that is 2^31-number_chars).
