Use this overload if you either really, really want strong ref
semantics for some reason or because you want to connect some
non-class method delegate. Whatever the delegates' context
references, will stay in memory as long as the signals
connection is not removed and the signal gets not destroyed
itself.
Preconditions: dg must not be null. (Its context may.)
