What issue are you seeing?

Codex calls on rg for file operations, but then once the prompt has been finished, the background rg process continues running. I have to go into Windows Task Manager to manually shut it down or else high CPU/SSD activities will persist even though the prompt response is complete.

What steps can reproduce the bug?

Uploaded thread: 019ae7c9-b8cc-7473-ad24-6940c802f282

What is the expected behavior?

rg and any other processes that were triggered in response to a prompt would be shut down once the prompt is responded and completed.
