There was a problem hiding this comment.
OK, would be good if you can look for similar instances and fix them in one pass here.

Agreed, and we might also consider making the broadcasted variable compatible with some Automatic Resource Management to avoid such leak (like https://github.com/jsuereth/scala-arm). |

If that's just a Scala version of try-with-resources, it is unfortunately insufficient. It's not clear when the broadcast is actually no longer used because it may be used in computations that are computed lazily, or recomputed when something fails. Here the scope of the broadcast is clear though. |
