how about Timeout ?
pardon this crude example,

botp@jedi-hopeful:~$ cat test.rb

require 'timeout'
a=(1..10).to_a

STDOUT.sync=true

a.each do |e|
  print "> "

  begin
    Timeout.timeout(5) do
      x=gets
      puts "you entered: #{x}"
    end
  rescue Timeout::Error
  end

  puts e
end

botp@jedi-hopeful:~$ ruby -v test.rb
