Some of these issues are tricky to test, e.g. some of the code about
transferring predicate locks to a new target doesn't get exercised
unless an index page gets split while there are concurrent
transactions holding locks on that page.

I have not been able to find a good way to test these other than
system-level testing using a concurrent workload (usually the DBT-2
benchmark). I'd certainly be open to suggestions!
