Python keeps track of number of references to every object if the object has more that one reference by the time you use "del" the object is not freed, only number of references is decremented. Print the number of references for all the objects you think should be freed after each cycle/iteration, if is not equal 2 that means you are holding extra references to those objects. You can get the number of references to any object by calling sys.getrefcount(obj) -- http://mail.python.org/mailman/listinfo/python-list
