Not sure who else still is getting mails from the comments list - the following came today and fits right into our current discussions.

> In MPI 3.0, is MPI_Get_address subject to the same threading rules as other MPI calls?  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?
