     7  // In a concurrent garbage collector, one worries about failing to mark
     8  // a live object due to mutations without write barriers or bugs in the
     9  // collector implementation. As a sanity check, the GC has a 'checkmark'
    10  // mode that retraverses the object graph with the world stopped, to make
    11  // sure that everything that should be marked is marked.
