1. Check if your host supports semaphores (see below how)
2. If yes, set locks to use semaphores.

How to test. Copy the code line below to the file with php extension to the 
server and call it in the browser:

<?php echo function_exists('sem_get') ? 'yes' : 'no' ?>

The script will say "yes" if semaphores are supported. Semaphores are more 
reliable and faster than files.
