Okay.  I would think the code would avoid heapify when the caller does foolish things with this API such as:

SortedSet ss = filledSortedSet();
PriorityQueue pq1 = new PriorityQueue(ss.comparator(), ss);

PriorityQueue pq = filledPriorityQueue();
PriorityQueue pq2 = new PriorityQueue(pq.comparator(), pq);


I assume this constructor is going to be added to TreeSet, PriorityBlockingQueue, and ConcurrentSkipListSet?
