Dan reviews chapter 10 since we didn't get to that at the F2F Forum in Chicago in May.

[x] Question about dynamic process model. Should we change this name? No. that's the consensus.
[x] Do we need to return to MPI_INFO_ENV sentence about may also be queried following.... Marc Andres' ticket for info objects will impact this.
[x] Should we add a caveat/info to users for MPI_THREAD_SINGLE when initializing a session.
[x] text around MPI_Session_finalize including the process. Maybe add references to MPI_XXX_FREE?
[x] process sets - modify per Ryan's info changes (buffer length in C).
[x] 10.4.1 - maybe don't call it an MPI process since its not initialized yet. Add MPI before finalization.
[x] remove dup double in table in 10.4.1
[x] add query thread etc. to the `MPI_IS_THREAD_MAIN to the table and add list in 10.6 reference.
[x] add a bit more about number of psets that can be returned from MPI_Get_num_psets. Something about never go down.

possibly enhance advice to implementors in the MPI_Abort definition. (Punt this to fault tolerance working group
