Aye, I had some kind of sleep deprivation mental block on this 
function getting called repeatedly for the same buffer with 
different lengths. Imagine, instead, 10k separate buffers and a 
_single_ call of this function on each with a random length. In 
this case the reallocating calls would be the same with/without 
the fix.
