I don't think I can practically do that in the general case, because
heres the chain of objects that are created when, say, a search is
requested through LDAPConnection.

   LDAPAsyncOperation / LDAPSearchOperation  -> LDAPSearchResults ->
   LDAPEntry -> LDAPAttributeIterator

and each of these classes needs in-order finalization or I end up with
a connection being teared down but the thread still going on..
