// This test is a derivative of the Splay benchmark that is run with a variety
// of different GC options. It makes for a good GC stress test because it
// continuously makes small changes to a large, long-lived data structure,
// stressing lots of combinations of references between new-gen and old-gen
// objects, and between marked and unmarked objects.
