I'm trying to see if valgrind can see anything, but nothing from
ompi_init_preconnect_mpi is coming up (although there are some other
warnings).

I currently have a numerical model that, for reasons unknown, requires
preconnection to avoid hanging on an initial MPI_Allreduce call. But
when we try to scale out beyond around 1000 cores, we are unable to
get past MPI_Init's preconnection phase.
To test this, I have a basic C program
