Obviamente, no todo es "pickleable":

Tendrías que realizar un barrido del diccionario de variables, comprobando el 
tipo (con 'isinstance'), para distinguir las variables que se puedan pasar al 
pickle.

De todas formas, dudo que ésta sea una buena idea. Debes controlar mejor los 
objetos que a serializar si no quieres acabar teniendo un entorno 
completamente corrompido e inestable.
