store: Do not require mutable references to the store.

  - The only mutable reference that we need is to the reactor core,
    which we store in a RefCell anyway.  Requiring mutable references
    makes using the store very awkward, because the borrow checker
    works on lexical scopes, not dynamic scopes.
