Comment (by SimonKing):
It seems that the reference somehow comes from constructing the algebraic
closure, as we have
{{{
sage: K = GF(31)
sage: del K
sage: L = [c for c in gc.get_objects() if isinstance(c,
sage.rings.finite_rings.integer_mod.NativeIntStruct) and
len(c._get_table())==31]
sage: len(L)
0
}}}
So, the !NativeIntStruct can be garbage collected when we do not construct
the algebraic closure.
How can one find a reference chain from the algebraic closure to the
!NativeIntStruct?
