Just FYI: I can confirm that we're setting paffinity properly in the orted's:

[8:38] svbu-mpi:~/svn/plpa % mpirun -np 3 --mca mpi_paffinity_alone 1 plpa-taskset -p self
pid 12391's current affinity mask: 1
pid 12395's current affinity mask: 2
pid 12396's current affinity mask: 4
[8:41] svbu-mpi:~/svn/plpa %
