After some small adjustments to some comments and reducing the number
of iterations in test_random_offset_operations(), I pushed the patch.

The 10000 iterations were pushing the test time to about 91ms, which
seemed like quite a big jump from the ~28ms that it was taking on my
machine.  With 1000, it takes 36ms, which seems like a more reasonable
increase.

Thank you all for the reviews and feedback.
