After asking about this issue on #guix, cbaines pointed to this relevant thread: https://lists.gnu.org/archive/html/bug-guile/2021-12/msg00011.html. Ludovic mentioned it is known that forking processes in threads would be undefined behavior in POSIX, but that doesn't match what the worker code is currently doing, which is to fork *then* spawn threads. Christopher mentioned perhaps something to try is to call execlp in the primitive-fork new process; this seems to work reliable for them in the guix-data-service.
