A node I found describes how to do it manually, this is a minimalistic module that adds a button to the admin interface.

Executing a background process

<?php
$handle = background_process_start('mymodule_dosomething', $myvar1, $myvar2);

$handle = background_process_start(array('myclass', 'mystaticfunction'), $myvar1, $myvar2);

$handle = background_process_start(array($myobject, 'mymethod'), $myvar1, $myvar2);

$handle = background_process_start_locked('dontrunconcurrently', 'mymodule_dosomething', $myvar1, $myvar2);
?>

Executing arbitrary http requests

The following code shows how to fetch data via http in "parallel" (asynchronous non-blocking mode)
It uses an API similar to that of HTTPRL but "slightly" different, in order for the caller to gain more control of the requests. Plans to join forces with HTTPRL are in place.

Drupal way: blocking/synchronous

<?php
$r = array();
for ($i = 0; $i < 10; $i++) {
  $r[] = drupal_http_request('http://www.example.com/stuff/' . $i);
}
print_r($r);
?>
