Whoa!  I'll take that big tuple read-only any day.  :)

Of course, the tuple is only good if:

- only one process needs access to it (as otherwise it'll be cloned
  in every single process, unless you use single heap?)
- its read only

Man, I never thought that the difference would be that big though.
