(Get the code!)
After some more digging I found out that qemu also has this very issue, but it happens a bit differently. In particular, this very same winXP test guest freezes in upstream qemu with -enable-kvm on _shutdown_, not on restart. In qemu-kvm it happens on restart but not on shutdown.
And bisecting plain qemu leads to this commit:

main: force enabling of I/O thread
As far as I remember, qemu-kvm always had iothread enabled, that's why the bug initially was only reproducible on qemu-kvm.
