As far as i can tell the subprocess is added with scheme_add_managed. Patching this to *_close_on_exit changes the behavior to what the OP expect. I'm not sure if close on exit or not is the better default for subprocesses, better ask Matthew what his intentions were.<br>

I would expect the custodian to shut down all of its managed resources when Racket exits, and not just with an explicit shutdown. What are the cases in which one wants to avoid shutting down a resource on exit?<br>
