- Why? Because the bit is the leftmost bit of a word
- which contains a 'length' which is always a positive value
- so that bit is never set to 1 (otherwise it would be negative)
-
- Given the above, we have two choices : either we ignore the
- size of the header itself and just look at the pxdbed field,
- or we check the size and then we (for safety and paranoia related
- issues) check the bit.
