Subject: How to restore input from within a loop or similar?

Hi,

I currently have a pseudo irc client.

I use something like this here to get what I type:

  select( [$stdin], nil, nil, 1.5 )

I do this from within a big loop that reads in user input, like so:


loop {

  user_input = $stdin.gets.chomp
  case user_input
  when 'test'
    puts 'Just testing...'
  when 'irc'
    # here the code to start the IRC client, which has that select()
call
  end
  break if user_input == 'quit'

}


My question is, when I input 'irc', how do I stop only that select()
call, and return control back to the user_input loop?

Right now, if I use "exit" within the IrcClient class, I stop the whole
program, but I only want to stop the Irc client
