[mpi3-coll] array parameters in nonblocking collectives

[Anthony Skjellum]

It appears to me that mpi should temporarily  "control"(own) the passed by reference data structures from the point the call is made to the time of completion... Users should accept this as part of the contact and shouldn't assume they own this data during the call's lifetime... From a state transition diagram perspective, ownership passes to and from mpi at ifunction and wait call, respectively.
