I'll let Shawn comment on this.  The realloc() does not seem to
be using the contents in the buffer from the previous round, so
I suspect that a free() followed by an independent alloc() would
be an improvement when the later call uses much larger buffer
than the previous one, but would be a waste if the later one
needs smaller buffer.
