ROS2 for real-time applications

rclcpp needs to be memory audited, e.g. if there are usages of STL containers, we need to use memory allocators for them (e.g. https://github.com/foonathan/memory )

Would it be reasonable to write a static analyzer for checks like this? (As far as I know there is none yet.)
