Thanks, I suppose when the mutator is doing evacuation as part of LRB, it's actually helping the collector. To that extent, using the collector partition for that makes total sense. I just wanted to know what the situation was. This makes sense, and existing documentation is sufficient now that this aspect of terminology is clear. Thanks!
