When the poll loop's safety-net timeout fires (poll_count > max_poll_count), the background subagent task was abandoned without cancellation or cleanup, leaving a stale entry in _background_tasks indefinitely. The original code had a comment promising "the cleanup will happen when the executor completes", but run_task() in executor.py never calls cleanup_background_task after reaching a terminal state -- the promise was never implemented. This change mirrors the asyncio.CancelledError path: signal cooperative cancellation via request_cancel_background_task and schedule _deferred_cleanup_subagent_task to remove the entry once the background thread reaches a terminal state. Direct cleanup at poll-timeout time would introduce a race: run_task() could remove the entry while the poll loop is still mid-iteration, causing a spurious "Task disappeared" error. The deferred approach avoids this by waiting for terminal state before removal. Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> |
