=== Testing VMs are disposable

It's important to think of VMs like cattle. If they become lame you just shoot
them and let vagrant reprovision them. Say you've hosed your precise VM:

----------------------------------------------------

      @Nullable Object instance, Invokable<?, ?> invokable, int paramIndex, Class<?> testedClass) {
    /*
     * com.google.common is starting to rely on type-use annotations, which aren't visible under
     * Android VMs and in open-source guava-android. So we skip testing there.
     */
    if (Reflection.getPackageName(testedClass).startsWith("com.google.common")) {
      return;
    }

   * intentionally, so there is no other way to clean up these threads. (The better solution,
   * though, would be to run the tests that use TestThread in separate VMs so that their threads
   * don't hang around during other tests.)
