I must be missing some important point here. If an MPI implementation
truthfully claims to be thread-safe then clearly it cannot be invoking any
calls which are themselves not thread-safe. And if an MPI implementation is not
thread-safe then it doesn't matter what it functions it calls internally
because threads aren't going to be compatible with it anyway. So why exactly do
we need to add any new text?
