Block sizes are unsigned 32-bit quantities; don't stuff them into an int.
*Especially* don't stuff the amount of remaining data in a block into an
int that will then be passed to file_skip() as an amount to skip ahead,
as a Really Large Value will turn into a negative value and produce
various forms of bizarre and tricky-to-debug behavior.
