What were the improvements? First, Racket now tells you the end of the machine code for a jitted procedure with `scheme_jit_find_code_end` (so messing about with guessing the size is no longer needed) and it also can JIT on-demand (so you don't have to call a function before disassembling it) with `scheme_jit_now`.
