Ruby Threads Example

#!/usr/bin/ruby
f1 = STDOUT
t1 = Thread.new {
  f1.puts "Thread 1 started"
  25.times {|n|
    f1.puts "Thread 1 is writing #{n}"
    sleeptime = rand(100).to_f/100
    sleep sleeptime
  }
}
t2 = Thread.new {
  f1.puts "Thread 2 started"
  25.times {|n|
    f1.puts "Thread 2 is writing #{n}"
    sleeptime = rand(100).to_f/100
    sleep sleeptime
  }
}

f1.puts "Joining threads, if you had not joined, the main program would have quit here, thereby killing the threads before completion"
t1.join
t2.join
