Is it possible to get a copy constructor for archive::archive? Better still, 
would it be possible to have an "archive archive::isolate()" function to 
obtain a copy of an isolated archive without writing it to disk? That would 
give an opportunity to run empty methods on a small copy of the archive in a 
concurrent thread.
