Comment (by akaariai):
Looks good (although I haven't done a full review). Skipping deferred
model handling is OK, it does actually contain some possible issues (load
deferred model, set attributes from a form, save() must work). I think
this could be dealt with, but lets just leave it out for now.
The pre/post save signal should get a new argument. There is some
precedence to adding arguments to signals ("using" in 1.3 for example) so
this should not be impossible to do from backwards compatibility point of
view. The .save() is also documented to take kwargs, so changing save's
signature should be OK, too.
