<h2>mem_r.c -- memory operations</h2>
<blockquote>
<p>Qhull uses quick-fit memory allocation. It maintains a
set of free lists for a variety of small allocations. A
small request returns a block from the best fitting free
list. If the free list is empty, Qhull allocates a block
from a reserved buffer. </p>
<p>Use 'T5' to trace memory allocations.</p>
