You could mitigate some race conditions by using the StripedLock class in the cache loader, but this will only prevent races on the cache loader on a single instance.  In a cluster, we'd need some sort of distributed locking to do this - either that, or for S3 to support transactions.  :-)

Hmm, a good reason then to have the tests disabled by default for automated test runs, etc.
