Side note for the constructor and destructor discussion: should we be more 
widely marketing the __cleanup() infrastructure that Peter added a year or so 
ago? It likely helps a lot with at least some of these cases. In systemd we use 
__attribute__((cleanup)) pretty widely and my experience is that it's made the 
code a lot easier to both create and consume.
