 * collected or not (weak references).
 * mono_gchandle_new () is used to prevent an object from being garbage collected
 * until mono_gchandle_free() is called. Use a TRUE value for the pinned argument to
 * prevent the object from being moved (this should be avoided as much as possible 
 * and this should be used only for shorts periods of time or performance will suffer).
 * To create a weakref use mono_gchandle_new_weakref (): track_resurrection should
 * usually be false (see the GC docs for more details).
 * mono_gchandle_get_target () can be used to get the object referenced by both kinds
 * of handle: for a weakref handle, if an object has been collected, it will return NULL.
