Here's a sample script that does most of the sorts of stuff I was doing
apart from database work.

Note how long it takes to exit after finishing.

#! /usr/bin/php -q
<?php

ini_Set("max_execution_time","0");
ini_Set("memory_limit","500M");

class thingy {
  function thingy($c) {
    if ($c>0) $this->ref=&new thingy($c-1);
  }
}

$stash=array();
$max=500000;

$start=time();

for($i=0;$i<$max;$i++) {
  $r=rand(0,300);
  $stash[$r][]=&new thingy(rand(0,10));
  echo "\rUse: ".floor($i/$max*100)."% ";
}
echo "\n";

$mid=time();

$max=count($stash);
$c=0;
foreach(array_keys($stash) as $key) {
  unset($stash[$key]);
  $c++;
  echo "\rFree: ".floor($c/$max*100)."% ";
}
unset($stash);
echo "\n";

$done=time();

print "Use: ".($mid-$start)."\n";
print "Free: ".($done-$mid)."\n";


?>
