I was just going back to that patch. The current savings are 24 bits (so
now you see why I considered making 'interned' a type - to get that bit
in without paying for a whole byte :-).
Before the nitpickers point it out: yes, the average savings are likely to
be less than 24 bits because of allocator overhead and nonuniform
distribution of string lengths.
