title: in php5, wish to send email in different process
body: <p>in php5 web app, getting email address from user and sticking it into database, but want to send the email without user waiting for the email to complete.  using gmail, sometimes takes a few seconds.</p>
  
  <p>thinking about <code>fopen( "http://self.com/mailer.php", "r" )</code>, where <code>mailer.php</code> would do the actual mailing.  will this work?</p>
