Try this:

def greet
  puts 'hello'
end


threads = []

5.times do |i|
  threads << Thread.new do
    sleep(rand() * 10)
    puts "thread#{i}"
    greet
    puts
  end
  puts "loop#{i}"
end
puts

threads.each{|thr| thr.join}

--output:--
loop0
loop1
loop2
loop3
loop4  #Note that all loop iterations are completed

thread3
hello

thread0
hello

thread4
hello

thread1
hello

thread2
hello
