Yeah. Actually the odd thing about it is that the crash seemed to
invariably be on conflicting pgbench_accounts updates, which is a fairly
low-contention table in this test design (but the bug turned it into
high-contention). What I would have expected is crashes on the very
similar updates to pgbench_branches, which is designed to be
high-contention. It might be that there is some other effect going on
here that explains why that wasn't happening. Need to go back and look
more closely.
