I developing on a software operation state indicator in my .screenrc as a backtick. The software uses ROS PUB/SUB so I would like to run the backtick program in the background and have the indicator update when the operational state changes. According to the docs:

"If both the lifespan and the autorefresh parameters are zero, the backtick program is expected to stay in the background and generate output once in a while. In this case, the command is executed right away and screen stores the last line of output. If a new line gets printed screen will automatically refresh the hardstatus or the captions."

I noticed that this background backtick program does not exit when screen exits. Is that working as intended or is that a bug?

Let me know if you need me to provide more specific information for reproducing this bug.
