Description:
------------
Hi,

imap extension doesn't work with apache2 (2.0.50) compiled with the option --with-mpm=worker. The same script works from the php cli or if apache2 is compiled with the default mpm-prefork.

imap_open() doesn't try to open the connection and exit with the error reported immediatly.

the same error appears if I try to connect to an imap server.

Reproduce code:
---------------
<?
  error_reporting(E_ALL);

  $mbox=imap_open("{mail.somedomain.com:110/pop3}INBOX", "username", "password");
  if ($mbox) {
    print "OK\n";
    imap_close($mbox);
  } else {
    print "ERROR\n";
  }
?>


Expected result:
----------------
The connection is right and I can see on the mail server the connection.

Actual result:
--------------
Warning: imap_open(): Couldn't open stream {mail.somedomain.com:110/pop3}INBOX in /disk1/servizi-abbonati/test.php on line 4
ERROR 
Notice: (null)(): Can't connect to mail.somedomain.com,110: Error 0 (errflg=2) in Unknown on line 0
