Ann,

Thanks for you always clear (of a complex thing in the engine internals
that I don't know how works) description.

Could not agree more with you.

I ask to know why it is a bad idea, I know your opnion abou transaction
isolation, and I could bet that you consider dirt read something very
very bad (like a random number generator :-) ). But, could it be a tool
that could bring power to the user when he needs it ?

My brother, has a daugther (almost 2 year old) he says "Don't be fooled
by his angelical face ! She is more dangerous with a plastic knife (the
kind that comes inside industrial cakes) in the hands than a
professional murderer with an rifle with a silenciator". So I just
dreamed about what she can do with an axe. :-)

I don't see personal offense in the above statement, no problem.

But here in Brazil are pretty hot, just take another trip here to enjoy
our summer :-)
