Looks like my case really was just VASP’s fault, and really I’d call it a VASP 
bug (you shouldn't call mpi_finalize from a subset of the tasks).  Yours is 
similar, but not actually the same, since it’s actually trying to stop the 
task, and one would at least hope that OpenMPI could detect it and exit.
