Comment (by jdemeyer):
For the `dokchitser` failure, there is some annoying global state (which
is probably a bug) in the `computel.gp` script. For example, in the
doctest
{{{
sage: E = EllipticCurve('389a')
sage: L = E.lseries().dokchitser()
sage: L.num_coeffs ()
156
sage: L.derivative(1,E.rank())
1.51863300057685
sage: L.taylor_series(1,4)
2.90760251490292e-20 + (-1.64772944938078e-20)*z +
0.759316500288427*z^2 - 0.430302337583362*z^3 + O(z^4) # 32-bit
2.90614059330736e-20 + (-1.64690098288532e-20)*z +
0.759316500288427*z^2 - 0.430302337583362*z^3 + O(z^4) # 64-bit
}}}
removing the `L.num_coeffs ()` test changes the last results.
