Ah, right. I agree that we probably ought to run the ci as non-root.
However, if the test requires non-root, it probably needs to be marked
with the SANITY prereq.

I also ran into one funny thing: if you run the script with "-i", then
we do not run the test_when_finished block. And therefore the "ro"
directory is left without its write bit, and the next test run fails, as
it cannot "rm -rf" the old trash directory out of the way.

I'm not sure there's a good solution, though. Skipping the
test_when_finished block on a "-i" run is intentional, to let you
inspect the broken state.

Are we sure this was the problem on Travis, and it wasn't just an issue
with how I reproduced via docker?
