ack'd. I also took another look at the changelogs and don't see anything
that looks obvious or makes
me think it isn't a race.

test_tracemalloc_track_race segfault (qemuarm64-musl)
  - v6.18.32 → .33 has 55 mm/kernel commits, including 1dcd36420af2 futex:
Drop CLONE_THREAD
    requirement for private default hash alloc and several sched/fair
tweaks that affect timing

That  could nudge a race test toward a fail, if the test was flaky before.

functional_ipc_shm (qemux86-64-musl libc-test)
  - No ipc/ changes in v6.18.32 → .33. Kernel-side SysV shm code is
untouched.
  - A quick search found me a few hits on.libc-test's ipc_shm has what
looks like known intermittent
   issues in some emulated arch + c library combox

I can try a bisect between  .32 and .33 if we get it to happen again, I'll
get setup for testing in case
it does fail again or becomes a common intermittent issue.
