Model.all.each instead of Model.all.run.each

[hakunin]

I think that doing

Model.all.run.each { |m| ... }

Puts all the models into an array and thus if you have many many of them, you will go over the allowed memory on appengine.
Doing this, would be much nicer memory wise:

Model.all.each { |m| ... }

But thats not supported in my version of Mirah datastore.

I rewrote my query to use the bassic AppEngine API and I was able to go through 80k+ rows in a single request, thats pretty impressive. We should have that ability too :)
