[Seaside] Redirecting to an error page etc., if an exception is caught using WAListenerAdapter

If I don't use that adapter then I cannot use Comet. I thought ST
exceptions were raised before any stack unwind, so why has the stream
been committed before the exception fires? Is the only solution to let
the browser hang, and have the user refresh?
