# cleanup and as a post-shutdown last-resort if scripts/linuxcnc's own
# SIGTERM trap could not reap everything in time.

# SHM_KEYS mirrors SHMEM_KEY in scripts/runtests:157. If a ui-smoke
# crash leaks any of these, the next runtests invocation aborts in
# test_shmem(); we must clean the full set.
