It might depend on which operating system and/or Ruby version you are using.
I tried the code underneath on Windows Vista, using the Ruby Windows versions,
and Ruby. It works for me using Ruby 1.9 for Windows.
But using Ruby 1.8.6 and using the JRuby 1.8 equivalent seemed to work,
or rather not work, in the way you described in your latest post.

require "timeout"
def gets_timeout( prompt, secs )
puts
print prompt + "[timeout=#{secs}secs]: "
Timeout::timeout( secs ) { gets }
rescue Timeout::Error
puts "*timeout"
nil # return nil if timeout
end

rr = gets_timeout "Do not input. Wait for timeout. ", 5
p rr #=> nil
rr = gets_timeout "Input something before timeout: ", 10
p rr #=> "something\n"

I tested my version in Ubuntu and it worked fine.

At least for JRuby, we can't do a proper select on stdio because the
JVM does not provide such a capability. So timeout can't interrupt
stdio.
