Hi Steve,
Here's the histogram internals documentation I promised awhile back (second patch).
Accompanying it is a new config option that enables a new hist_debug event file, which is used by the examples in the doc to display some of the histogram internals (third patch).
The first patch is just a cleanup suggested by Masami that I previously missed.
Thanks,
Tom
