El código de salida, el cierre automático de la `Session` en:

...se ejecutaría después de que la response termine de enviar los datos lentos:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[30:38] hl[31:33] *}

Pero como `generate_stream()` no usa la sesión de base de datos, no es realmente necesario mantener la sesión abierta mientras se envía la response.
