I have a node that has quite a long clearup process to perform on exit, involving file IO etc., that takes a minute or so. However, at the moment, the only way I can work out to allow it to do this without timing out is to modify DEFAULT_SIGINT_TIMEOUT in my ROS install's nodeprocess.py file (https://github.com/ros/ros_comm/blob/melodic-devel/tools/roslaunch/src/roslaunch/nodeprocess.py). This is not ideal for many reasons (easy for someone else using the node to miss, involves changing the timeout for all nodes on the system, etc.).
Is there a better way to do this, per-node, e.g. in the launch file?
