Comment: 

Most of my previous comments have been fixed, thanks. I still disagree
with the authors on one point, but not enough to delay the draft:

In section 3.1.1 "2-step 6P Transaction" there seems to be a rare race condition
if A's timeout expires while B's Response is in flight. This will be detected
later as an inconsistency (section 3.4.6.2). The authors don't think it's necessary
to mention this in 3.1.1. IMHO it would be useful to mention. (Similarly for
section 3.1.2, 3-step transaction.)
