+        This is an Apache1 mod_php-only directive that forces an Apache child to exit if a PHP execution timeout occurred.
+        Such a timeout causes an internal longjmp() call in Apache1 which can leave some extensions in an inconsistent
+        state. By terminating the process any outstanding locks or memory will be cleaned up.
