> Currently we have two hooks in the split flow of a region. PreSplit() and
> postSplit(). But not always these are helpful in case i have a problem in
> preSplit() or postSplit() i need to do a rollback of the current region or
> the region that i am handling thro the hooks.
> So its better if we have a hook in the rollback code and also one final hook
> say postCompleteSplit() so that CP can take any corrective action.
> Pls do suggest if i can provide a patch for this.
