The MPI standard says that MPI_Abort makes a "best effort". It also says that an MPI implementation is free to lose the value passed into MPI_Abort and deliver some other RC..
The standard does not say that MPI_Abort becomes a valid way to end a parallel job if it is passed a zero.
To me it seems pretty clear the name MPI_Abort is was chosen to imply failure.
I think modifying the standard to be explicit about what must happen when MPI_Abort is passed zero would be an option. It is a ugly one in my view but it would give this kind of application the equivalent of MPI_Quit.
Right now, someone who passes a zero to MPI_Abort would have a hard time claiming his application is valid.
