commit    bdaabb9b22caa71021754d3967b4032b194d9880
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Thu Jul 07 21:36:30 2011 +0000

    There's a small window wherein a transaction is committed but not yet
    on the finished list, and we shouldn't flag it as a potential conflict
    if so. We can also skip adding a doomed transaction to the list of
    possible conflicts because we know it won't commit.
    
    Dan Ports and Kevin Grittner.
