I see.  I wasn't aware that site generation had to be done in any particular
order.  If the result at the end of the generation is the same whether you
use a Set or a List, I don't see the advantage.  (I am playing devil's advocate).

If you run into errors due to the order of processing, I could understand--
then again I would want to know why there was an order enforced in the beginning.
Basically all we are doing is treating the CLI version like the Servlet version.
Requests can come in any order.

My only point is this, a lot of work went into a minor change that could have
been spent on some of our more major issues.  I wouldn't back out the change
now, though.
