[Mpi3-hybridpm] Fwd: [Mpi-comments] Thread synchronization for MPI_Get_address

[Jeff Hammond]

Jeremiah should definitely sign up for this list.  I agree that this
function and ones like it should be considered as part of our holistic
analysis of thread-safety requirements, to the extent that this is not
already implicit from what Bill and Rajeev have proposed already.

In particular, in MPI_THREAD_SERIALIZED mode, am I required to ensure that MPI_Get_address is not called at the same time as itself or other MPI code?  If it does require synchronization currently, would it make sense to change that requirement to be looser?
