There was a lengthy discussion about it last year, the conclusion of which was
that it's a product of the way processes are handled in the Windows
environment, and that, since the same limitations don't exist under Linux,
buffering should not be implemented. A number of disadvantages were also
pointed out, including the unnecessary complexity that it introduces and the
problems it creates in dealing with Web applications which update the HTML
content without reloading the page - exactly the kinds of applications for
which Aria has been created.

I think the discussion was on the mozilla-accessibility list; you might find
it helpful to look at their archive.
