The usual way I use realloc is to maintain separate counts of the number
of array elements I have allocated, and the number I am actually using. A
realloc call is only needed when the latter hits the former. Every time I
call realloc, I will extend by some minimum number of array elements (e.g.
128), roughly comparable to the sort of array size I typically end up
with.

And then when the structure is complete, I do a final realloc call to
shrink it down so the size is actually that used. Is it safe to assume
such a call will never fail? Hmm ...
