As the MPC Sage code is written right now, calls are made to mpz_pow_si,
mpz_pow_z, or mpz_pow, depending on the type of argument. Each of these
are still 5-6 slower than Sage's complex number type.

I mean: each of these calls (mpz_pow[_si|_z]) results in operations that
are 5-6 times as long as Sage's complex type (~35 microseconds vs. ~200
microseconds).
