That's still the case.

But this was an easy bug: the size field in TableA was overflowing  
(patch below). TableB and TableC should probably also get int sizes. I  
can now route! Yay!

Also, the first byte of the tables header should rather be  
tabC.getSizeSize() -- it's sort of the number of bytes of the Table C  
size field which follows Table B. "Sort of" because 0 means there's  
still one byte (also 0).
