Here's a different intermittent assertion on Netbsd from test-aio-multithread:

MALLOC_PERTURB_=${MALLOC_PERTURB_:-$(( ${RANDOM:-0} % 255 + 1))}
tests/test-aio-multithread -m=quick
-k --tap < /dev/null | ./scripts/tap-driver.pl
--test-name="test-aio-multithread"
PASS 1 test-aio-multithread /aio/multi/lifecycle
PASS 2 test-aio-multithread /aio/multi/schedule
assertion "QSLIST_EMPTY(&ctx->scheduled_coroutines)" failed: file
"util/async.c", line 279, function "
aio_ctx_finalize"
ERROR - too few tests run (expected 5, got 2)
