I found 14/25 in your git tree. Very satisfying to see all the
scaffolding vanish for process_measurement() :)

I like this progression in 4-14; I find it much much easier to review.
My only complaint is the variable names. I think I'd prefer "blob" over
"le" or "l", which are both contain very little information about what
they are.
