Since Python 2.0, the CPython does periodic mark-and-sweep garbage collection, to collect objects that are unreachable despite having a non-zero reference count (i.e. they are part of an unreachable reference cycle). I guess this is what you're thinking of? See http://docs.python.org/lib/module-gc.html (note the caveat about objects with __del__ methods). http://docs.python.org/lib/module-weakref.html may also be of interest. -Andrew. _______________________________________________ coders mailing list coders@slug.org.au http://lists.slug.org.au/listinfo/coders
