It seems a lot saner to make it a part of registration than adaptation. 
The 'persist' argument to __call__ never made sense to me. Think about a 
what the objects involved "know": if an object knows that it wants an 
adapter and it wants it to persist, it can just keep a reference to the 
adapter it gets back.

OTOH, we don't currently support marking an adapter persistent at 
registration time, do we? I say don't add features that don't have clear 
use cases yet.
