Subject: buffering of $stdout

Hi list!

I'm new to ruby, so be nice to me ;)
I want to capture everything written to the strout and get it in a 
variable. So I did this:

stdout = $stdout
stdoutin, $stdout = IO.pipe

puts "Hello World"

tmp = $stdout
$stdout = stdout
$tmp.close
variable = stdoutin.readlines.join("\n")

It works, but if I write to much, the pipe seems to be full and the 
script hangs. It will never continue, because I start reading from the 
pipe when everthing is written. My idea is to start two theads, one for 
writing and one for reading, but maybe somebody knows a easier way.

Please help!

Johannes
