I'm a bit nervous about this.  Generally problems physically writing to
the device are pretty bad and lead to followon hard to debug problems as
the chip state drifts from the state the software thinks it has.  If
this is a good idea I'd really like to see more analysis as to why this
is expected to happen and why it's OK.
