We have problems with edit conflicts too. I opened two
sections of <http://it.wikipedia.org/w/index.php?title=Wikipedia:Sondaggi>, I made
an edit in the first
<http://it.wikipedia.org/w/index.php?title=Wikipedia:Sondaggi&diff=450468&oldid=450467>
then in the second
<http://it.wikipedia.org/w/index.php?title=Wikipedia:Sondaggi&diff=450469&oldid=450468>.
First edit was overwritten but I didn't get an edit conflict.
AFAIK edit "conflicts" with yourself are intentionally ignored; I
guess it is supposed that you know what you are doing. Although I
guess that the idea to _merge_ the changes if there is no merge
conflict would be a wiser one.
