I apologize i am going to take this back, lets please hold the series for now.

In pursuit for the effect on events, Pedro and I spent a few _hours_
chasing this - and regardless of the events, there are still
challenges with the concurrency issue. The current reproducer
unfortunately cant cause damage after patch 2, so really patch 6 was
not being tested. We hacked the repro to hit codepath patch 6 fixes.
We are not sure what the root cause is - but it certainly due to the
series. Peilin, Pedro will post the new repro.
