So, let me tell a little success story while using the "GC-proof" 
resource classes.
I tested the above idiom on some code I was a bit liberal with 
and with no thought gone into clean-up.
I found all resource leaks in ~1 hour, and there was several of 
them.

The open question that remains is: "can ~this() really be called 
multiple times?", that would made the idiom less ugly (had to add 
boolean flags for most resources).
