Josh -

In general, I think everything looks ok. However, the "right" thing
doesn't happen if the CM PML is used (at least, when using the Portals 4
MTL). When configured with:

  ./configure --enable-mca-no-build=pml-ob1,pml-bfo,pml-v,btl,bml,mpool

The build segfaults trying to run a SHMEM program:

mpirun -np 2 ./bcast
[shannon:90397] *** Process received signal ***
[shannon:90397] Signal: Segmentation fault (11)
[shannon:90397] Signal code: Address not mapped (1)

mpirun noticed that process rank 1 with PID 90398 on node shannon exited
on signal 11 (Segmentation fault).
