              Calling this API while the same command is called from another thread, may result
                  in one of the two scenarios:
              1. The command will wait (internal) until the previous command finish, and then be executed.
              2. There are not enough resources and SL_POOL_IS_EMPTY error will return. 
              In this case, MAX_CONCURRENT_ACTIONS can be increased (result in memory increase) or try
              again later to issue the command.
