As Thorsten pointed out, the documentation says it all.
Summed up:
it allows for a visual representation of computation "intensity" of the
scene being rendered; and since it is a red/green (no blue) image it's
suggested use is for height fields, though getting a scene together for
one in this way is not exactly easy to shape if you want to form a
height field.
Other than that, I haven't seen any other uses myself.

Well, it is nice to know what parts of a complex scene it is that takes most
resources...
I've done it many times, to try and find out where to add some variables to speed up
test
rendering... (#if(fast=true) #else #end)

If the information is output to a .CSV file, you can then input that file into
a program that handles distributed rendering. It can use the information giving
which parts of the output image are more processor-intensive to work out a more
optimal sub-division in terms of which CPU's render which bits.

Good use for the "histogram"!
