# indefinitely, and with no per-test timeout it took the whole run down with it.
# A SelectorEventLoop is aiortc's documented requirement on Windows. The
# trade-off: SelectorEventLoop cannot spawn subprocesses on Windows, so the
# ffmpeg/ffprobe streaming tests fail here rather than pass and need a per-module
# Proactor override or skipif(win32). Set at import, before any loop is created;
# no effect off Windows, where the default policy already works for both.
