Be more cautious about shrinking the nursery
Looking at benchmark output I see the nursery growing and shrinking a lot. Often there will be a collection with a low promotion rate that causes the nursery to shrink followed by a collection with a high promotion rate that causes it to grow again. It would be good to stop it bouncing around like this.
The patch only shrinks the nursery when the promotion rate is below the threshold for two consecutive collections. This seems to be quite effective at reducing the bouncing.
