+ * malloc_stress:  Stress the heck out of malloc(), and do a lot of
+ *                 sanity checks that the malloc()'ed buffers are legit.
+ *
+ * usage:  malloc_stress [options...]
+ *
+ * Default:  Do random-sized malloc() calls until malloc() returns NULL
+ *           or some signal kills the process.
+ *           Randomly do a free() 10% of the time.
+ *
+ * Options:
+ *    -min #bytes   malloc() at least #bytes per malloc() call.
+ *    -max #bytes   malloc() no more than #byte per malloc() call.
+ *    -mem #bytes   Stop when #bytes has been allocated.
+ *    -calls #      Stop when #calls to malloc() have been executed.
+ *    -time #sec    Stop if the number of seconds has elapsed.
+ *    -seed #       Set the random seed to #.
+ *    -free %       Randomly free() some % of the time.
+ *    -dbg          Dump internal structures (could be voluminous!)
+ *
+ * Exits with status code:
+ *    0    PASS
+ *    1    FAIL (plus lots of stdout output)
+ *    99   Illegal arguments or internal error.
