My opinion is that the important step here is to fix the behaviour before
alpha-3 or beta (whatever cames first).

So, it's nice your idea to rename context.copy() to context._shallow_copy(),
make context.copy() deep, and then, in all the tests that fail, change copy
for the shallow one.

Later, we'll have time to maybe fix that and don't depend of a shallow copy
(work around that WorkRep would be nice also).
