The reason is that this will cause a crash:
TbInterfaces foo = TbInterfaces("blah");
It relies on the generated copy constructor (or assignment operator), which copies the
pointer values from a temporary object. After |foo| in this case has been initialized
with values from the temporary object, the temp goes out of scope and is deleted.
The result is that |foo| has been initialized with pointers do a deleted object.
Also fixing expectations for the return value of VoE Release() calls after I checked
in my change that makes the VoiceEngine per-object ref counted and not per-interface.
