Those two classes are exactly the same as those in "sfcache" folder
-------------------------
CLockCrud.class.php
CSfCache.class.php
-------------------------

The only modified file is this:
-------------------------
CLockCtrl.class.php
-------------------------

Just one line(return true;) is inserted after lock function's declaration:
-------------------------
	public function lock( $path, $mode, $rw = "r" ) {
return true;
-------------------------
This "return true" will disable locking feature.
