 You may want to connect a event listener asynchronously of the emiter creation.
 In such case you have lost the previous events but you may still need the
current values.
 A event handler has to handle that case to be usefull.

 For input->intf case, a thread to dispatch events would be really great for
example (of course this should be configurable per emiter).
