Discuss some items from last week's MPI Forum and issues opened subsequent to the Forum:
Briefly discuss chapter committee work for upcoming MPI Forum in Bristol. Dan says Bill Gropp will cover edit changes, e.g. macros etc.
Discuss https://github.com/mpi-forum/mpi-issues/issues/732
Ken verified that MPICH does not hang in MPI_Comm_disconnect if inactive persistent requests associated with a communicator had not been freed. However, Open MPI does hang in this case. We need to check about MPI_Finalize in this scenario. If there would be an impact by adopting changes proposed in #732 it would be the change in behaviour for MPI_Finalize.
The proposal in the issue is associated with the 'C' option in issue 710.
Discuss as well the datatype issue that came in with PR #832 (see related issue https://github.com/mpi-forum/mpi-issues/issues/710). Dan says the changes in PR reflect what is implied with the current state of the sessions and MPI handles that are not directly associated with MPI_COMM_WORLD or a particular session. Howard will open a new issue specific to this datatype issue, including some possible proposals.
