[Mpi3-bwcompat] ticket 265 udpated

[Fab Tillier]

Hi Folks,

I've updated ticket 265 with the comments from the last meeting.  Please take a look.  We'll go over the PDF on Friday (right David?) and hopefully agree that it's ready to send out for wider review.

TBD still (I think) is whether to split it into two tickets, one for the basic functionality, the other for the new 'w' collectives.
