Is there any plans to make working signals in D?

My memories tell me that I was never able to make a _thread safe_ weak
reference, though. I don't remember exactly, but I think that it was
because the dispose event happens after all threads have already
restarted. This means that some thread could extract a strong reference
from the weak reference before the weak reference knows that the
underlying object has been destroyed, thus creating a dangling pointer.
