@Stack, Actually, this is an old bug in fb-89 branch only. No need to fix it in trunk.
Also attach the fix here.

> There is a serious bug in the multiget which will cause the multiget function only returns
part of the results.
> In the process function: 
> The initial region is set before sorting the input list.
> So after the input list has been sorted, the initial region may no longer be the correct
region for the first row in the sorted list.
> So the first row in the sorted list may be sent to the wrong region server which has
no result for this row.
