Surely it's no coincidence that this happens to be 2**33 - 1.

Seems like an endianness issue. I've confirmed that the actual number
of rows affected can be calculated from the `rowcount` attribute as
follows:

real_rowcount = given_rowcount >> 32

Further, the following relationship holds:

real_rowcount, 2**32 - 1 == divmod(given_rowcount, 2**32)

I would imagine this is an easy fix.
