I just tried it with qemu-system-x86_64, and with that I can observe a 
noticable performance gain using TB chaining as well. Maybe it's simply 
a lot more effective in system than in userspace emulation.

Anyway, having implemented it for BRC already, I might as well leave it 
in for future generations to enjoy.
