Title: Guarantee a successful index read before reading block data

Guarantee that we've got a token from the index lookup before we go ahead and try to read that block. (mirrored buffer cache)

This makes crashes like this one https://github.com/rethinkdb/rethinkdb/issues/52 cleaner and easier to debug.
