As a workaround, you can take most DOM accesses out of the loop - this makes
the code run really fast. In my example, this suggestion corresponds to:

function selectd() {
   user = document.fmain.user;
   domain = document.fmain.domain;
   useroptions = document.fmain.user.options;
   domainoptions = document.fmain.domain.options;
   for (var i=0; i < useroptions.length; i++) {
          if (domainoptions[i].value == useroptions[user.selectedIndex].value)
{
                 domain.selectedIndex=i;
          }
   }
}

Speaking about a possible fix in WebCore, looks like the lengths of
HTMLCollections need to be cached better.
