It seems that the reipl step blocks anaconda to finish. It waits with the "Installing bootloader" window and "... Writing autokickstart file" as last message in anaconda.log indefinitely. When I made the doReIPL() function a no-op, I got the final Congrats&reboot screen.
This doesn't appear to be a problem with F17 installs. Please re-open if you see it again.
