      Description

      NEWHPROF: RFE: Object age and ability to determine sort order

      This doesn't have to go into hprof necessarily, but something that jfluid
      does would be handy to try. Count the GC's with GC_FINISH event, and add
      the current GC number to object creation, and/or create an average age
      of all objects allocated at a site. Then include this data in the summary.
      In other words, provide some more help in finding leaks by providing more
      data about the objects. Ideally, the tool could perhaps list the most likely
      objects that could be leaks? Just a thought.

      Also, probably worthwhile to allow different sorts of the data, it's
      pretty fixed right now.

      Now perhaps what should happen is that the output should be done in XML
      or some basic table form, and some kind of viewing tool could be used to
      view that output, selecting the sort criteria after the collection.
      Perhaps at runtime with the data sent down a socket or transport mechanism.

      just ideas I didn't want to forget about.
