Hmm. I wonder how we never got this one from a rand config.
Anyhow, give we are near the end of this cycle, I'll take this for
the next merge window rather than rushing it through.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

Thanks,

Jonathan
