Interesting. I checked this on several machines. They actually say
different things.

Redhat 9- bi: Blocks sent to a block device (blocks/s).
Latest Cygwin- bi: Blocks sent to a block device (blocks/s).
Redhat 7.x- bi: Blocks sent to a block device (blocks/s).
Redhat AS3- bi: blocks sent out to a block device (in blocks/s)

I would say that I probably agree, things should be relative to the cpu.
However, it doesn't seem to be something that was universally agreed
upon. Or maybe the man-pages were all wrong, and only got updated recently.
