Blocking IO in Windows threads

ruby-talk

Under Linux the following code from Dave Thomas doesn't block.

Thread.new do
   loop do
     puts "You said #{gets}"
   end
end

10.times do
   sleep(1)
   puts "Say something"
end

But under Windows with the latest one-click installer, it does.
Any ideas on how I can do something similar on Windows? It also doesn't seem to have "io/wait".

Thanks
