|   155719 [zedshaw@ze s] Actually, this would be the *best* way to do this.  You just register the whole damn pool with the GC and never unregister it.  Then you do your own memory management and control.  The GC is completely cut out of the picture and can't mess with your gear.  The only thing you need to do is just not declare a free function for the ruby object.
