title: PHP library to ease creation of processes (fork)
body: <p>Do you know any library that eases work with processes, signal sending etc? Thank you in advance!</p>
  
  <p>EDIT:
  We're doing some data loading from external sources in PHP daemon. We want to split PHP process to have:</p>
  
  <ul>
  <li>one process for loading per every data source,</li>
  <li>one process for processing data that came from every data source.</li>
  </ul>
