it deletes them when the *sender* is deleted. It doesn't know what the lambda 
does, so there's no way to tell to delete when one of the variables inside the 
lambda becomes invalid.

In Qt 5.2, you will be able to associate them also with a receiver, in which 
case the connection will be deleted when either sender or receiver is deleted.

To do more complex things, keep the return result from connect() and use it to 
disconnect.
