-// The following routines allow the browser to aggressively cleanup NPObjects
-// on a per plugin basis.  All NPObjects used through the NPRuntime API should
-// be "registered" while they are alive.  After an object has been
-// deleted, it is possible for Javascript to have a reference to that object
-// which has not yet been garbage collected.  Javascript access to NPObjects
-// will reference this registry to determine if the object is accessible or
-// not.
-
-// Windows introduces an additional complication for objects created by the
-// plugin.  Plugins load inside of a DLL.  Each DLL has it's own heap.  If
-// the browser unloads the plugin DLL, all objects created within the DLL's
-// heap instantly become invalid.  Normally, when WebKit drops the reference
-// on the top-level plugin object, it tells the plugin manager that the
-// plugin can be destroyed, which can unload the DLL.  So, we must eliminate
-// all pointers to any object ever created by the plugin.
-
-// We generally associate NPObjects with an owner.  The owner of an NPObject
-// is an NPObject which, when destroyed, also destroys all objects it owns.
-// For example, if an NPAPI plugin creates 10 sub-NPObjects, all 11 objects
-// (the NPAPI plugin + its 10 sub-objects) should become inaccessible
-// simultaneously.
-
-// The ownership hierarchy is flat, and not a tree.  Imagine the following
-// object creation:
-//     PluginObject
-//          |
-//          +-- Creates -----> Object1
-//                                |
-//                                +-- Creates -----> Object2
-//
-// PluginObject will be the "owner" for both Object1 and Object2.
-
-// Register an NPObject with the runtime.  If the owner is NULL, the
-// object is treated as an owning object.  If owner is not NULL,
-// this object will be registered as owned by owner's top-level owner.

-// Unregister an NPObject with the runtime.  If obj is an owning
