Due to a recent and awesome pull request by Jeremy Cline, it is now possible to run
Bodhi's unit tests with about 1/10th the RAM they used to take (they went from about 4
GB to about 450 MB!) Because of this, you can now lower the amount of memory required in
your Vagrantfile if you wish. There's a PR open to make the default 2 GB, but I
think you could squeak by with even 1 GB.
