One bug report describes search_files on a single file hitting \`\[Errno 3\] No such process\` on macOS, attributed to a getpgid ESRCH race in the native rg lane. Two pull requests appear to address related cleanup behavior (treating an already-exited child's group cleanup as a no-op and preserving native rg results after ESRCH), but their outcomes are not established here.
