Even that has a problem if power goes down in the middle of the reset vector
being re-written.  I handle this by the bootloader always being run from
reset.  It only runs the application if the remaining memory passes a
checksum.  Otherwise it remains in bootloader mode, and the host can't do
much else than try another upload.
