Hoppy next year!

yes dudes! it's next year this year now! time go bye quckly so I use time some times. I try good thredding scheduler, but catch big bug!

#!/usr/bin/ruby
require 'rubygems'
require 'openwfe/util/scheduler'
include OpenWFE

scheduler = Scheduler.new
scheduler.start

scheduler.schedule_every('2s') { p Time.now; sleep 4 }
scheduler.schedule_every('3s') { puts '3 seconds later..' }

scheduler.join


- it no work like think! it put 3 seconds later only one time not every time! what givings?
