If a page is requested and it's not present in the cache it must be 
generated. If during the generation a second request for the page is 
done that process will also try to generate that same page.

To prevent this a lock can be created for the generation of this page. 
The setting lockingMode lets you set the method that is used for this:

String: Define which locking mode is used to control requests to pages 
being generated. Can be one of either "disable" (no locking), "simple" 
(checks for file existance), "flock" (using PHPs flock() function), 
"semaphore" (using PHPs sem_acquire() function). Default is "disable".
