More breakage to come :). But that can be sorted out.

I bet that timed polling was just to work around early fragility of the
iothread code /wrt TCG. qemu-kvm does not poll either (but uses an
"interesting" mixture of !IOTHREAD and private code instead...). The
conversion makes sense, though I haven't looked at every detail.
