addition of a new instance. That means that all Instances are checked at the smae time, non depending
on when they were added.
* Because the DATA_AVAILABLE bit of the status of the DDS Reader is reset on first read, the DATA_AVAILABLE
bit can be zero even if the DDS Reader still contains unread data. For this reason the ROS entities are
showing data_available until the first empty read after the DATA_AVAILABLE bit is set.
This has the inverse effect, that even if the DDS Reader has no more data it is showing DATA_AVAILABLE
(since a empty read has to be done to reset the bit). This trait has to be taken into account.
The ros_action_server, for instance, will for instance remove a goal entering terminal state, if the
MAX_GOALS limit is reached
