The 1.8mb is the size of our excutable, which implements the language
(MzScheme).  Things that are defined in the language get jitted
(through lightnin), and are not included in the executable itself.
If we'd jit through LLVM, then the executable would need to include it
too.  (The 1.8mb includes the lightning-based jitter now.)
