Yep, we both seem to be saying that we'd like these features, but we
don't want to see them become delay-points.

Not sure. It seems like 2PC will be required/desirable within the year
for better support of some clustering scenarios, so we "might as well
look at it now". When I was reading Satoshi's stuff a while ago I
thought it was a protcol level thing, not a SQL command level thing, but
don't really care either way. :)
