Here are some items that are perhaps suitable for MPI-2.2
* MPI_Reduce_scatter_block
* (possibly) built-in segmented Scan operations (new binary operators)
* Correction/clarification to semantics of one-sided synchronization
when switching between modes (NOTE: the proposal I posted some months
back is deficient, as Rolf pointed out to me, and will have to be modified)
I will try to make final proposals before the next meeting
