Pry threading test

pry-threads.rb

require 'rubygems'
require 'pry'
#require 'rbtrace'
puts $$

threads = []
threads << Thread.new do
  loop do
    puts "Thread 1"
    sleep 1
  end
end

threads << Thread.new do
  pry
end   

threads << Thread.new do
  loop do
    puts "Thread 2"
    sleep 1
  end
end

threads.each {|t| t.join }

Another way to fix this with rvm:

rvm pkg install readline
rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

Also works for other versions of Ruby.
