FWIW it's easy to make the issue reproduce faster with following diff

diff --git a/contrib/amcheck/t/003_cic_2pc.pl b/contrib/amcheck/t/003_cic_2pc.pl
index f4255c1fb8..0d68c53387 100644

I.e. if pgbench exits earlier than we call finish() it always hangs. I observe reproduction on my Drogonfly VM and I can share VM state if it's of any help.
