+/// This uses the priority_queue adaptor class to provide the queue
+/// as well as the ordering scheme while allowing us access to the
+/// raw container if we follow a few simple rules.  One of the more
+/// important of those rules is that any iterator becomes invalid
+/// on element erasure.  So pay attention.
+///
+/// Threading:  not thread-safe.  Expected to be used entirely by
+/// a single thread, typically a worker thread of some sort.
