I've had to raise my php memory limits much further than I'd like just to get some normal things done in D7. The admin page for Drupal's menu system with a large menu tree can easily crush what I'd consider a healthy amount of available ram. Here is a fast and ugly fix settings.php:
$path = explode('/', $_GET['q']);
if ($path[0] == 'admin') {
ini_set('memory_limit', '192M');
}
Hopefully this is sufficient for most cases.
