Subject: Timeout lengthy external executable

Hi all,
I'm new to Ruby, I'm trying to use it to create a script where I launch
some executables.
I'd like to timeout if one of them takes too long, I'm using IO.popen to
launch the exe.
The problem is that the timeout doesn't seem to work, so if my
executable hangs for some reason I have no way to stop it and go on.

Is there something I can do?
If I use "system" instead of IO.popen it works but I need popen to parse
stdout

I include a simplified code of what I'm doing (no parsing)

Thanks in advance for any tips on that
Bye

 begin
    timeout(5) {
      IO.popen(command_media)
      }
     puts "Timeout didn't occur"
 rescue Timeout::Error
     puts "Timed out!"
 end
