docs: The current process reserves a certain number of instances. If there are not enough instances available, the
          process is made to join a queue. When this method returns, the process holds the instances it has requested to
          take.
  
          :param num_instances:
              Number of resource instances to take.
          :param timeout:
              If this parameter is not ``None``, it is taken as a delay at the end of which the process times out, and
              leaves the queue forcibly. In such a situation, a :py:class:`Timeout` exception is raised on the process.
