In an implementation that implements continuations with continuation-passing
style, the size of the continuation not necessarily any larger than what you
would build by hand (unless you forget something by hand :-).

The continuation stores
  - lexical bindings, analogous to the declared state except it's implicit
  - a code pointer, which is needed if your program has more than one
    resumption point and doesn't take much space anyway given that the
    program is already on the server.
