[bug] use dict keys to iterate
We ran into a RuntimeError yesterday on this line, the callback can modify this dict and make the iteration raise an error. Using keys method to iterate is safer. See http://stackoverflow.com/questions/11941817/python-runtimeerror-dictionary-changed-size-during-iteration-how-to-avoid-th/11941855#11941855
