bq. I found they failed last time because I ran the tests both on my local
machine and the AWS EC2 vm using the same S3 bucket at the same time, which is
not supported I believe. Sorry for the last confusing comment.
No worries! Yes, we try to do our best on test isolation within a single mvn
run so that multiples test suites can run in parallel, but we don't currently
attempt to isolate for multiple concurrent mvn runs against the same bucket.
For some test suites, like the root path tests and the multi-part purge tests,
it would probably be impossible.
