I've been very busy with at work, and haven't had much time to work on the
2-phase commit patch.

I'm keeping a close eye on Alvaro's nested transactions stuff, because it
touches the same areas as 2-phase commits.

One day, while reading postgresql code, I realized that my two-phase
code doesn't do the right thing with snapshots. GetSnapshotData scans
through all running backends, and collects the xids of all running
transactions. I suppose all pre-committed transactions should go to the
snapshot too.

So there's still some work to be done, but I'm still hoping to finish it
in time for 7.5.
