PHP throws 'Allowed memory exhausted' erro

I'm trying to setup a tiny sandbox on a local machine to play around with Drupal. I created a few CCK types; in order to create a few nodes I wrote the following script:

chdir('C:\..\drupal');

require_once '.\includes\bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
module_load_include('inc', 'node', 'node.pages');

$node = array('type' => 'my_type');

$link = mysql_connect(..);
mysql_select_db('my_db');

$query_bldg = '
  SELECT stuff
  FROM table
  LIMIT 10
';

$result = mysql_query($query_bldg);

while ($row = mysql_fetch_object($result)) {

 $form_state = array();

 $form_state['values']['name'] = 'admin';
 $form_state['values']['status'] = 1;
 $form_state['values']['op'] = t('Save');

 $form_state['values']['title'] = $row->val_a;
 $form_state['values']['my_field'][0]['value'] = $row->val_b;
 ## About another dozen or so of similar assignments...

 drupal_execute('node_form', $form_state, (object)$node);

}

Here are a few relevant lines from php_errors.log:

At this point any action php takes results in the last error shown above. I tried increasing the value of memory_limit in php.ini before the final Fatal error which obviously didn't help.

How can the error be eliminated? Am I on a correct path to migrating data into Drupal or should the cck tables be operated on directly?

If you're trying to migrate data from sql (or anywhere else), you'll find doing your own direct import is fairly complicated. Have a look at this method: http://www.lullabot.com/articles/drupal-data-imports-migrate-and-table-wizard

WHat exactly is that 'node_form' call doing? I'm guessing it's that $form_state data and building some huge in-memory structure from it. That means:

a) You have to increase (or eliminate) the memory limit - Drupal's building something big, and you're not giving it the headroom to work

b) Change the node_form stuff so it builds smaller chunks at a time. Maybe flush output to the client at intervals? Save to disk?
