I should have added that a

gc.collect()

would probably be a good idea to have at the end of that flush() method.  I 
also noticed that the Out[] object isn't really correctly flushed, only the 
_NN variables are deleted (that code was probably written before Out[] existed 
as a proper cache).  Just some pointers...
