[Dev] Re: refcounted: my last comment

[John Anderson]

I'm grateful to Andi for releiving the burden of manually calling 
SetPinned, which I think is too error prone to be used in Chandler.

That said, however, I think his choice of the default will not make 
Chandler more portable (since it's using refcounted), nor will it change 
people's preference for not manually calling SetPinned -- it will only 
make it more likely that we'll have a rare bug because someone forgot an 
obscure argument to the repository. But, as Katie points out, this is a 
very minor issue we can easily live with. Whether or not we port to 
another language, the real issue is that manually calling SetPinned is 
too error prone. It is better to solve this problem in a portability 
layer or with some other system wide mechanism, rather than manually 
calling SetPinned.
