Another interesting data point:

./sage -t -verbose devel/sage/sage/rings/polynomial/toy_buchberger.py
<SNIP>
Trying:
    Ideal(g1).basis_is_groebner()###line 44:_sage_    >>> Ideal(g1).basis_is_groebner()
Expecting:
    True

Result: hang

And:

./sage -t -verbose devel/sage/sage/rings/polynomial/multi_polynomial_element.py
Trying:
    k.factor()###line 1035:_sage_    >>> k.factor()
Expecting:
    (s^2 + 2/3) * (x + s*y)^2 * (x + (-s)*y)^5 * (x^2 + s*x*y + s^2*y^2)^5

Result: hang

Cheers,
