Description

https://github.com/ros-controls/ros2_controllers/pull/26
https://github.com/ros-controls/realtime_tools/pull/57

Instead of calling create_wall_timer (which starts a new thread iirc) for each new action goal, runNonRealtime should be decoupled from its object and spinning at action_monitor_rate. And this loop should be able to handle each new goal action goal sent.

Research direction

Start by reviewing the linked ros2_controllers and realtime_tools pull requests, then trace create_wall_timer, runNonRealtime, and action_monitor_rate in the goal-handle implementation. Done means the monitoring loop handles each new action goal without creating a wall timer and its behavior remains correct at the configured rate.
