can someone tell me the behaviour of these two programs run in separate
terminals under windows?

     harp:~ > cat a.rb
     system "mkfifo fifo >/dev/null 2>&1"   # don't know how to do this in win
     File::chmod 0777, "fifo"

     t0 =
       Thread::new do
         loop do
           open("fifo", File::RDONLY|File::NONBLOCK) do |fifo|
             f = select([fifo]).first.first
             STDERR.print f.read
           end
         end
       end

     t1 =
       Thread::new do
         loop do
           STDERR.puts 42
           sleep 0.42
         end
       end

     gets


     harp:~ > cat b.rb
     loop do
       open("fifo", File::WRONLY) do |f|
         f.puts 'forty-two'
       end
       sleep 0.42
     end


i expect the output to look something like:

   42
   42
   42
   42
   42
   forty-two
   42
   forty-two
   42
   forty-two
   42
   forty-two
   ...
   ...


cheers.
