Cassandra integration tests hang if whirr's scripts bucket is missing

I don't know if this is specific to cassandra or just a general issue.

I ran the integration tests as part of building the 0.2.0 release candidate. The tests failed while verifying cassandra. Looking on the ec2 host I see the following in the stderr (nothing in stdout). Note - I had not created the 0.2.0-incubating bucket on s3, so while this test would never pass, it seems unusual that the test hangs forever rather than tear down the test and report an error (I had to ctrl-c to stop the test, then manually cleanup ec2).
