Zero. Does that prove anything?

Well, my blatant statement probably deserved such a reply. :-)

I don't want to go into details here. It's just various issues you
mentioned yourself, together with my own considerations: It turns out
that implementing persistence in the "real world", with persistance
barriers to the non-persistent core and to the outer world, you have to
deal with many issues you hoped to avoid and that wouldn't exist in a
perfect all-persistent world.

I'm not claiming persistence is bad. It may be very well that the total
amount of problems to solve in a persistent system turns out to be
smaller than in the opposite case. Yet it seems to, must be roughly of a
similar order.

Just wanted to point out that persistence is not a magic silver bullet
solving many hard problems for free.
