php + windows and fork

does anyone know a method to use PCNTL under windows? found the following link http://in.php.net/manual/en/ref.pcntl.php#37369

but thats not up to date anymore...

the reason for that is that php doesn't support threading. but my app have to do more than one job at the same time. so i have to create child processes for every job ... but that seems to be a problem under windows ...
