I don't think this is the correct thing to do. The Apache HTTP client used by `AmazonS3Client` via `AmazonHttpClient` has connection pooling. This would effectively disable the pool while tying up sockets, etc., used by the pool. We should figure out why the pooling is not working and fix it directly.

We probably just need to pass a `ClientConfiguration` with a larger `maxConnections` value when creating `AmazonS3Client`.
