Hi All,

We've had some discussion on naming of the helper threads routines and 
have generated the following interfaces for discussion in today's telecon:

Original        Version I                    Version II
MPI_Team_join   MPI_Team_register            MPI_Team_register
MPI_Team_leave  MPI_Team_execute_deregister  MPI_Team_execute(int coord)
MPI_Team_sync   MPI_Team_execute
MPI_Team_break  MPI_Team_deregister

Where "coordination" argument can be one of:

Version I adds symmetry between join/break and similarity between 

Version II merges leave, sync, and break into a single call.  This 
version would also allow an implementation to define other coordination 
mechanisms that could be specific to a given system.  For example 
"MPI_TEAM_EXECUTE_WHILE_IDLE" could give a thread back to the 
application if a message arrives.
