May I suggest to keep this new C-modules in separate branch, not in 
bzr.dev until it goes mature?

Because having C-modules require to compiling it and this is create some 
difficulties on windows (where C-compilers is not default part of 
installation).

As compromise I suggest to make new C-extensions optional and give a 
chance to bzr to works even without it. I did not look at your patch so 
probably you already provide this option.

Or new phase of bzr development means that 0.8.2 is latest stable bzr 
version for windows users (without having pain with compiling 
C-extension) for some time (probably months)?
