test_process_teardown forks a child process while the parent has an
active zmq/asyncio context (ZeroMQ's own docs call forking with a live
context+IO-thread undefined behavior); under qemu's slower/different
scheduling the forked child intermittently dies with exit code 1
instead of exiting 0. Reproduces reliably on target but never locally
(isolated, whole-file, or whole-suite runs all pass), consistent with
an environment-specific fork-safety issue rather than a logic bug.
