I'm not ruling out C++ altogether but at this stage, I can't see an 
incremental transition to C++ working all that well.

I tried to isolate the device models and have a well defined interface 
between the C and C++ code but the trouble is that if you want the C++ 
side of things to be Good C++ code, you end up having to replace large 
chunks of QEMU code.

It's possible that I just took the wrong approach.

My end goal is not C++, it's to improve the device model.  I haven't 
tried doing it with GObject yet but before we even get there, there's a 
lot of good we can do with glib.
