When members associated with a communicator finish jobs or exit, they have to
call mpi.comm.disconnect
to release resource if the communicator was
created from an intercommunicator by mpi.intercomm.merge
. If
mpi.comm.free
is used instead, mpi.finalize
called
by slaves may cause undefined impacts on master who wishes to stay.
