One question: does the randomization ever help when building a new
index? In the original test case, you repeatedly delete and insert
tuples, and I can see how the index can get bloated in that case. But I
don't see how bloat would occur when building the index from scratch.
BTW, I don't much like the option name "randomization". It's not clear
what's been randomized. I'd prefer something like
"distribute_on_equal_penalty", although that's really long. Better ideas?
