The key things to note:

1) this is a test with reboots, so we repeatedly call utah_is_done.py via ssh.
2) debugging this requires looking at the ssh log which isn't included in the build artifacts, but I was able to grab from the jenkins workspace:

We called utah_is_done.py about 50 times and then for some reason on this one attempt we have a line of code that's simply:

 import psutil

and that fails due to the no /dev/pts/1 error
