Jeff,

Again, thank you. BTW, I just noticed this in the docs:

> An app can perform a 
> query<http://code.google.com/appengine/docs/java/datastore/queries.html> 
> during 
> a transaction, but only if it includes an ancestor filter. (You can 
> actually perform a query without an ancestor filter, but the results won't 
> reflect any particular transactionally consistent state). 


That parenthetical is kind of important :) You won't get an error or 
warning, but you'll quietly lose consistency. I went looking for this 
because you kept saying "you can only do ancestor queries in a transaction" 
and I knew I was doing queries in a transaction without them - glad I found 
it.

I feel like I am keeping you from real work :) I do appreciate it.

Stephen
