My functions do print the memory usage;
I'm just wondering why the array returned is 1/5th of the desired (and
allocated) size.

$r = array();
$l1 = false;
if ($maxKeys!==null) {
$hmGenKeys = $maxKeys;
$l1 = true;
}
$hmGenKeys--;
if ($hmGenKeys<=0) return false;
if ($maxDepth<=0) return false;
if ($l1) {
srand(htmlMicroscope_randMakeSeed());
while ($hmGenKeys > 0) {
$hmGenKeys--;
$hmGenKeysDone++;
file_put_contents('countdown.txt',
'k:'.number_format($hmGenKeysDone,0,'.',',').
' m:'.number_format(memory_get_usage(true),0,'.',',')

htmlMicroscope_randomValue(4) => $next

break;

htmlMicroscope_randomValue(4) => htmlMicroscope_randomValue(20)
