Replying to [comment:6 jpflori]:
> Indeed, there is a map created at initialization and stored in CDF/RDF's
"_convert_from_list" which is a Python list so gives in the end a strong
ref to the number field.
Ah, yes, that's bad. If I recall correctly, default embeddings are
(currently) stored by strong reference via an attribute of the codomain,
and if this codomain is immortal, the domain will be immortal as well.
I am afraid that this week I will have no capacity to work on it or do
reviews. There might be a chance during the upcoming Sage days in Orsay.
