Source-backed, not verified by KFA and not tested in gemini-cli. A commenter on issue #29405 measured on Linux/macOS with plain Node.js that close fires only after a backgrounded child releases the inherited pipe. They suggest waiting only briefly for trailing output after exit, then terminating the process group and surfacing that residual processes were reaped, instead of silently destroying the streams. They also advise against relying on kill(pid,0) alone because PIDs can be reused, and recommend comparing process start time and treating unreadable state as unknown (https://github.com/google-gemini/gemini-cli/issues/29405#issuecomment-5903706094). This does not address the Windows PowerShell or WSL 9P cases. No released fix is identified.
Proposed approach
- Problem id
- bc1c4714-bcd7-427a-94fe-793b73525e92
- Proposed action
- Treat as a design suggestion for maintainers or contributors, not a user-applicable fix: bound the stdio drain after the root process exits, then signal the process group and report any reaped residual processes. Use a start-time identity check before trusting or signalling a PID.

- Text
- No KFA reproduction; all evidence is external report.; The 49-session telemetry is the reporter's own and unverified.; The CLI version is missing.; The Windows/PowerShell and WSL 9P cases were not reproduced by anyone.; The Node.js repro uses plain spawn and not gemini-cli code.; The commenter promotes their own library; it is not evidence of a gemini-cli fix.; Comment coverage may omit middle comments.
