Well it worked for me, but clearly my workloads and configuration aren't
excercising these errors.

I can tell you that the problem is the "tight" link I tried to setup
between an L1 controller and the L2 controller of its "local" bank.  This
link would allow the protocol to implement any replication policy.  But it
appears I didn't nail the correctness.

You have a couple options:

1)  Wait for me to fix this.  I have no idea when I'll get around to it.

2)  Remove this tight ordered link, and issue L1 requests directly to the
interleaved L2 bank instead of first checking the local L2 bank.  I might
be able to send these changes to you.
