Answering Kirill, V2 is somewhat more complex that in should be. Dave has 
raised the concerns about architecture already, I've agreed to them to a 
certain degree, but nothing happened. 

The problem is that the situation is like a deadlock. I can try to refactor as 
I implement feature, which I actually do. Another alternative would be to 
stop implementing features, and refactor to get a better architecture. Why 
not? Because I have some reservations

- No features/user-level improvements for a next milestone is just not good
- I am not sure that archiecture improvement will have noticable effect on 
involvement of other persons
- Even if I start refactoring, I might well refactor parts that *I* consider 
messy, and in a way that *I* consider right. Which might end up even more 
confusing for other people.

So, I did not have much motivation for a global refactorings. And because of 
that nobody dares to write significant patches. Deadlock?

I don't know how to resolve this. I can try to raise priority of refactorings, 
and there are some things that I wanted to improve for some time. But that 
also requires that other interested parties review my refactorings or suggest 
places to improve or help with this process. Without that, I might return to 
the current mode of operation. 

And, Dave, you say that "a few people I know who are actually motivated to 
make significant contributions". Can you tell who are they? My impression is 
that nobody has enough time. Some pretty simple and good ideas, like 
separating the build system in 4 layers, were never implemented, for example.
