And done.   All bundled up with a nice new tarball.   This one opens up a
another reporting option as well:

tests = RWB::Runner.new(urls, 1000, 50)
tests.report_header
tests.report_overall
tests.report_by_time


will create something like:
$ ruby -Ilib quick.rb
completed 100 runs
completed 200 runs
completed 300 runs
completed 400 runs
completed 500 runs
completed 600 runs
