Again, I can't reproduce the problem from the numbers below.  I get
head_size = 63.  (I was typing in the formulas into python...)

Perhaps the problem is that "float" doesn't have enough precision.
So, the first thing to try is replacing "float" with "double"
throughout probe_partition_for_geom().

If this still doesn't fix the problem, would you be able to trace
through the execution of this function?  (Do you know how to do that?)

You should get the following values:

        ratio = 254.0
        X = -130671.0
        Y = -2099229615.0
        cyl_size = 16065.0
        head_size = 63.0

Thanks,
Andrew
