Comment:
I've attached a patch that reverses the order: it first tries the
numerical algorithm, and if that fails, it then tries the algebraic
algorithm. This makes vastly more sense to me, since the numerical
algorithm -- if it will fail -- is likely to fail in a reasonable amount
of time, but the algebraic algorithm can succeed and take a huge amount of
time.
