Nothing like allowing the error in each estimate to
accumulate.

In practice, we've found Python to be somewhere between
30 and 100 times slower than C, clearly depending on the
algorithm and without really much effort to optimize.
(That is, our Python code could probably withstand
some significant optimization, if we cared to.)

Four times slower is, I think, unlikely without
significant optimization effort (or even then).
