This was off-list.  The point is, that with the iothread we don't need 
to rely on signals at all (qemu needs signals to break out of the 
emulation loop, kvm without iothread needs them to exit guest mode, but 
the iothread can simply sit in select() waiting for an fd to become 
active (or for aio to complete via a signal).
