Since you've stated the goal is to keep track of the total amount of
memory malloc()ed, then the sum of the two fields is what you're
looking for. Explicitly checking for zero in arena could lead to all
sorts of interesting behaviour. Consider the case where most of the
memory is allocated with mmap(2), but a small amount is allocated with
sbrk(2), for example.
