HA logs thread safety errors when Docker container is deleted and recreated

[airdrummingfool]

Hello and thanks for this great component!

I've been seeing "Error doing job: Task was destroyed but it is pending!" logged in my Home Assistant logs for a long time now. I recently learned that I could get detailed logs by enabling the debugpy integration in the HA config:

debugpy:

After doing so, I found a series of logs related to monitor_docker that I figured I should report. I think I was working on the tailscale image around this time, so the container was probably deleted and recreated a few times.
