Just out of curiosity ... how can it possibly be even a little bit sane
that fsm_local_map is a single static data structure, without even any
indication of which table it is for?
If, somehow, there's a rational argument for that design, why is it
not explained in freespace.c? The most charitable interpretation of
what I see there is that it's fatally undercommented.
