Comment (by SimonKing):
Replying to [comment:110 SimonKing]:
> If we use it, then I still think it makes sense to adopt Singular's
convention on that c-slot: It counts the number of references minus one.
OTOH, it really seems awkward: A fresh ring that we get out of libsingular
will have `.ref==0`. Thus, it is supposed to have a reference already. But
there is no reference yet.
