Unfortunately the feature isn't fully implemented yet with respect to interaction with the gc, thus the error message above. >What's the deal with that piece of code? The theory is that looping over the keypairs should be more stable, and somewhat faster (less memory accesses and reading memory sequencially). >-- >Sincerely, > Stephen R. van den Berg.
