  New Revision: 44222

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=44222

  Log:
    * ext/objspace/objspace.c (reachable_object_from_root_i):
      reachable objects should not include categories and
      category_objects because it is noisy information.
      In fact, objects created after calling
      ObjectSpace.reachable_objects_from_root should not be included
      as a returning hash objects. Currently, mswin64 platform has a
      problem because of this behaviour. Should we trace new objects?
