Comment (by was):
I tried this again today and:
{{{

sage: sage: R.<x,y,z> = GF(5)[]
sage: sage: f = 2*y^9*z + 2*x^2*y^5*z^3 - y^9 - 2*x^4*z^2
sage: sage: g = -2*x^2*y^9*z^4 - 2*x*y^3*z^11 - x^3*y^8*z - 2*x*z^8
sage: sage: h = f*g
sage: sage: time h.factor()

Wall time: 0.08 s
z * x * (y^9*z + x^2*y^5*z^3 + 2*y^9 - x^4*z^2) * (x*y^9*z^3 + y^3*z^10 -
2*x^2*y^8 + z^7)
sage: sage: time h.factor()
[... wait for minutes!!!!...]
}}}
So, again I say - WTF?
