Support for IMAP IDLE in net/imap

Ok, I have been stuck on it for hours. I thought net/imap.rb with ruby
1.9 supported the idle command, but not yet.

Can anyone help me in implementing that? From here, I though this would
work:

class Net::IMAP
def idle

cmd = "IDLE"
synchronize do
  tag = generate_tag

  put_string(tag + " " + cmd)

  put_string(CRLF)
end

end

def done
cmd = “DONE”

synchronize do
  put_string(cmd)
  put_string(CRLF)

end

end
end

But, when i issue imap.idle, it return true, but i have to press return
twice to get the server response. And there’s no notification for new
messages.

?> imap.idle
C: RUBY0005 IDLE
=> true

?>
?> S: + idling
