i would like to rewrite these integration tests to not use bash, maybe.

output from wget and tar, actually ends up in the stderr, which causes grunt-shell to fail. I can work around that by adding a -s in the wget call and get rid of the 'v' in the tar call. But i can't seem to get around the 'kill' process when shutting down the servers.

i noticed that the tests "fail" when i updated the grunt-shell plugin to the latest version since it now has failOnException and stderr defaulting to true.

i know we can provide our own callback in the options, let me play with that before we decided to scrap grunt-shell altogether
