"""is_safe_path refuses a relative path under an absolute base.

A relative path is resolved against the process's working directory, not
against base_dir, so whether it counts as inside depended on where the
process was started. test_stream_windows_traversal_blocked failed whenever
the checkout sat below the temp folder (the media base in tests), because
"C:/Windows/..." is a relative path on Linux. Every caller hands over an
absolute library path.
