Some vagrant commands will work on all VMs at once:

------------------
vagrant halt
vagrant destroy -f
------------------

`vagrant up` would normally start all the VMs but we've prevented that because
that'd consume a ton of ram.

=== Iterating on packaging tests

Because our packaging tests are capable of testing many combinations of OS
(e.g., Windows, Linux, etc.), package type (e.g., zip file, RPM, etc.),

### Action Required

   *
   * <p>This method has no effect (returns {@code this}) when called in GWT: it's unclear whether a
   * precomputed matcher is faster, but it certainly would consume more memory (which doesn't seem
   * like a worthwhile tradeoff in a browser).
