Pretty cool. I tried it with file-find. Here was the code:

require 'file/find'
require 'threadify'

rule = File::Find.new(
   :pattern =>  "*.rb",
   :path    =>  "C:\\ruby"
)

start = Time.now

rule.find.threadify(10){ |f|
   p f
}

p start
p Time.now

Without threadify, it took 1:40 on my laptop. With threadify(10) it
dropped to 44 seconds.

I think I'll add a "threads" option directly, and borrow some of your
code. :)

Thanks,

Dan
