Asterix, try this:

#---------------------------------

rd,wr = IO.pipe

Thread.new {
  loop {
    puts rd.readpartial(1)
  }
}

loop {
  sleep 1
  wr.write "+"
}

#---------------------------------

This works on Linux but I haven't tested it on Windows. And you're 
right, if you try to use Kernel#select in the reader loop, it doesn't 
work reliably! (I'm using a Ruby 1.8.4 snapshot from early June, which 
has changes in nonblocking I/O.) This may be a Ruby bug.
