I just took a look and it would seem that it can be acheived by commenting out one line

in /components/com_content/content.html.php

around line 2249 in my editor  (within the function editContent )

you can simply comment out the call for the second editor

Code:
editorArea( 'editor2',  $row->fulltext , 'fulltext', '600', '400', '70', '15' ) ; e.g.

Code:
// editorArea( 'editor2',  $row->fulltext , 'fulltext', '600', '400', '70', '15' ) ;
but instead, to give some more flexibity, I would place it in a conditional such as:

Code:
           if ( $_REQUEST['twoedits'] == "yes" ) {
    editorArea( 'editor2',  $row->fulltext , 'fulltext', '600', '400', '70', '15' ) ;
            }
This would allow a second link to be created with &twoeditss=yes added to the url which would give the two editor windows for you. (or you can just add it to the url in the browser for occasional use )

so if the normal link looks like
sitedomain/index.php?option=com_content&task=new&sectionid=1&Itemid=13
the optional link for reverting to two editor windows would be
sitedomain/index.php?option=com_content&task=new&sectionid=1&Itemid=13&twoedits=yes
