I don't see much about 2PC outside of twophase.c.
Regarding the original post, I agree that we should have two
phase-commit support for SSI. We opted not to support it for
notifications, but there was a fairly reasonable argument why users
wouldn't value the combination of 2PC and NOTIFY.
I don't expect this to be a huge roadblock for the feature though. It
seems fairly contained. I haven't read the 2PC code either, but I don't
expect that you'll need to change the rest of your algorithm just to
support it.
