Above is sample output from a test ember-cli app running ember s3:deploy pointing npm locally at the latest ember-cli-s3 add-on on master

I believe something with using the ext/promise.js library to make the S3 sdk putObject method thenable (here) is causing a context change in the AWS-SDK here

I'll need to figure out how I can safely make the putObject method a thenable to prevent the CLI from exiting while the files are uploading
