I have expanded a little bit on this issue here:
http://twoerner.blogspot.ca/2014/03/using-bmaptool-to-create-memory-card.html

and I see better what you mean about sparse segments. Using bmaptool,
theoretically, the same core-image-minimal should take the same ~20
seconds to write whether the image is 80MB or 4GB. The fact these are
significantly different suggests there might be room for improvement in
the way our images are created?

Still, I was able to go from 50 minutes to 14 when writing the 4GB image
using bmaptool versus using dd, so that's an improvement none the less.

Thanks for the tip!
