I suspect the issue here is the caveat described in the docs for `current-subprocess-custodian-mode`: Custodian-triggered shutdown is limited by details of process handling in the host system. For example, process and system may create an intermediate shell process to run a program, in which case custodian-based termination shuts down the shell process and probably not the process started by the shell. See also subprocess-kill. Process groups (see subprocess-group-enabled) can address some limitations, but not all of them. My guess is that running "racket" from a subprocess spawns additional processes that aren't controlled from the custodian. I noticed that if you change the program from "racket" to running "bin/cat", for example, the subprocess does seem to be terminated. (I don't actually know much about custodians so this could be all wrong) Cheers, Asumu ____________________ Racket Users list: http://lists.racket-lang.org/users
