Created an attachment (id=8882)
 --> (http://bugzilla.opendarwin.org/attachment.cgi?id=8882&action=view)
proposed patch

Use shared CollectionInfos for HTMLOptionsCollection and HTMLNameCollection,
too.

The test runs perfectly fast now. A test with 2000 options also runs fast (no
visible delay, a nice change from tens of seconds), but it still takes several
seconds to open, because the DOM version keeps changing, which defeats caching:
   for (var i=0; i < 2000; i++)
        document.fmain.user.options[i] = new Option("User " + i, i);

I couldn't understand why the other collections (images, applets, all etc.)
were returned from Document, but were only shared for HTMLDocuments. I just did
the same.
