Configures the number of additional mutexes to allocate. If an application will allocate mutexes for its own use, this parameter is used to add a number of mutexes to the default allocation.
                 The syntax of this parameter in the DB_CONFIG file is
                 a single line with the string mutex_set_increment, 
                 one or more whitespace characters, and the number of
				 additional mutexes. Because the DB_CONFIG file is read when the database environment is
				opened, it will silently overrule configuration done before that time.
