Sorry but how am I supposed to know that?!

I've read the whole patchset up until now and all text talks like *all*
*memory* needs to be accepted and before that has happeend, it is
unaccepted.

So how about you explain that explicitly somewhere, perhaps in a comment
above accept_memory(), that the unaccepted range is not the whole memory
but only, well, what is unaccepted and the rest is implicitly accepted?

And I went and looked at the final result - we error() if we fail
accepting.

I guess that's the only action we can do anyway...

You should try those before you paste them - it says "Not found" because
of the '/' in the Message-ID and it needs to be escaped.

This works:

Now I remember.

Thx.
