I'm looking at this part of your patch and I think it's far too big to
be a simple refactoring.  Would you split it up please?  I think the
StatsData / SimpleStat addition should be one patch; then there's the -b
changes.  Then there may (or may not) be a bunch of other minor
cleanups, not sure.

I'm willing to commit these patches if I can easily review what they do,
which I cannot with the current state.

Please pgindent; make sure to add /*--- here to avoid pgindent mangling

This part looks okay to me.  Minor nitpick,

+       int i = 0, w = 0, wc = (int) getrand(thread, 0, total_weight - 1);

should be three lines, not one.  Also the @W part in the --help output
should be in brackets, as FILE[@W], right?
