Subject: Re: [OMPI devel] RFC: initial MPI_T support

Let's bump it to Thurs - I trust what you say, but haven't had a chance to glance at the changes. Likewise, it would be nice to let Jeff return from vacation and look at it too.

We had some discussion at the forum about what level should be returned depending on which function is called first (MPI_T_init_thread or MPI_Init_thread). I don't think it was clarified what should be done but since it will be in future errata what is in the current implementation should be fine for now.
