This was submitted to qemu-devel ages ago -- 27-Aug-2010 according to my

I think the patch you proposed, Eamon, is the same as the one that
didn't work properly -- it's certainly a lot simpler than the two-part
patch that I wrote (and that patch has been in production for OracleVM
for a while, it seems solid).
