AIUI rendering a tile in mapnik does not render any other tile. The
situation with osmarender (where rendering a zoom-12 tile renders all
subtiles) does not apply to mapnik. So it's very possible to get a
patchwork of renderings. There's also no way to force a rerender of a
specific tile or area...

Have a nice day,
