Much too elaborate - I'm sorry, but I don't think anyone here is willing
to wade through nearly 900 lines of code. Can you break it down to a
simpler test case? Or try and break the schema I provided in my
previous message perhaps?

Works as expected in my schema when I tried it: T2 blocked at the insert,
waiting on T1. Once T1 committed, T2 threw an error, as the insert was no
longer valid. Using serializable or not, same result.
