What was the actual workload breaking with the bug? I ran a small variety and I couldn't reproduce it yet. I'm not saying there's no bug, I just would like to be able to test my version of the fixes...
It is not a minimal set, I don't know if all parts of this are necessary to rerproduce it. The whole crash-recovery cycling might not even be important.
I've reproduced it again against commit b2ed8edeecd715c8a23ae462.
It took 5 hours on a 8 core "Intel(R) Xeon(R) CPU E5-2650".
I also reproduced it in 3 hours on the same machine with both JJ_torn_page and JJ_xid set to zero (i.e. turned off, no induced crashes), so the fault-injection patch should not be necessary to get the issue..
