Comment(by zimmerma):
with Sage 4.7.2 I get the following:
{{{
sage: for p in prime_range(10^5):
....: K = GF(p)
....: a = K(0)
....:
sage: import gc
sage: gc.collect()
0
sage: from sage.rings.finite_rings.finite_field_prime_modn import \
....: FiniteField_prime_modn as FF
sage: L = [x for x in gc.get_objects() if isinstance(x, FF)]
sage: len(L), L[0], L[len(L)-1]
(9592, Finite Field of size 2, Finite Field of size 99767)
}}}
thus whenever we use the finite field we get a memleak.
(If I remove the {{{a=K(0)}}} line, I get only two elements in L, for p=2
and p=99991.)
