Works fine for me:

[pid 22777] starting up!
[pid 22778] starting up!

I am seeing an interesting failure on trunk. intercomm_create, spawn, and
spawn_multiple from the IBM tests hang if I explicitly list the hostnames to
run on. For example:
Good:
$ mpirun -np 2 --mca btl self,sm,tcp spawn_multiple
