Well, for things like race conditions I don't know that you can create
reproducable test cases. My point was that this bug was exposed by
databases with workloads that involved very high transaction rates. I
know in the case of my client this is due to some sub-optimal design
decisions, and I believe the other case was similar. My suggestion is
that having a test that involves a lot of row-by-row type operations
that generate a very high transaction rate would help expose these kinds
of bugs.
Of course if someone can come up with a self-contained reproducable test
case for this race condition that would be great as well. :)
