I tried this series with a Linux/m68k guest but network activity hanged 
the emulator. The cause of the problem is somewhere in this patch.

BTW, I've become suspicious of the word "rewrite". In this case I think it 
describes a commit that is attempting to do too much and needs to be split 
up to make it easier to review (and debug).
