The problem is that select statements will find rows not to be "there" because the snapshot scn is back in time, but as soons a you start working on current blocks, there is no problem. Shipping the current block will send also some scn across potentially (if needed , look 'redo ordering marks' in v$sysstat). I think that you should try the solution proposed by Oracle.
