Comment(by jpflori):
My point was that it seemed to me that there was some (not weak!)
reference in the dictionary ZZ._action_hash pointing to the
IntegerMulAction itself pointing to the curve and I thought it could
prevent garbage collection.
So I added a cpdef function to be able to clear that dictionary and see if
garbage collection occurs once it is emptied, however it is a the C level
so kind of the whole Sage library had to be rebuilt and I had to go back
home before rebuilding was finished...
Anyway, I'll have a look at it tomorrow :)
By the way, have you any idea if dictionaries declared at the C level such
as ZZ._action_hash are detected by objgraph ?
