Signal disconnect in pygobject

["KwangYul Seo" <kwangyul seo gmail com>]

Hello,

In pygtk, do I need to disconnect signal (event) handlers for cleanup? Does it cause memory leaks if  I don't disconnect handlers? 

In pygobject_connect() function in pygobject.c, it seems call pygobject_watch_closure. 

 * Adds a closure to the list of watched closures for the wrapper.
 * The closure must be one returned by pyg_closure_new().  When the
 * cycle GC traverses the wrapper instance, it will enumerate the
 * references to Python objects stored in watched closures.  If the
 * cycle GC tells the wrapper to clear itself, the watched closures
 * will be invalidated

Does this mean that when a GObject instance is freed, connected signal handlers are automatically freed?
