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.  :)
