Would ideally have liked a little more info on the 'why'. Was this previously
capped by practicality - i.e. not possible to read faster or is there
something else going on here?
Don't really need to know for the applied patch though so
Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
Thanks,
Jonathan
