Comment (by andrew.mathas):

 Hi Nicolas,

 I want to add to your proposal that the pickle_jar be properly documented.
 As far as I am aware, there is currently no documentation on what the
 pickle jar is for, how it should be used, and what to do when a pickle
 breaks with
 {{{
 sage -t  devel/sage-sf/sage/structure/sage_object.pyx
 }}}
 for example. A non-trivial example for using `register_unpickle_override`
 should also be added.

 Secondly, I think that the procedure for adding new pickles to the jar
 needs to streamlined. Again, I don't believe that it is described anywhere
 when or how this happens, but I do know that there are many "new" classes
 which are not represented in the pickle_jar with the consequence that the
 pickle_jar is unable to check backward compatibility for these classes.

 Andrew
