This just failed under WASI:https://buildbot.python.org/all/#/builders/1046/builds/4510/steps/7/logs/stdio . Maybe a flaky test?

Yes, a flaky test. It can fail even on Linux if increase the CPU load.

I am puzzled. The failure is not actually depended on the CPU load. It is random, with probability about one or few percents. An obvious way to fix it (increasing the time delta forutime()) does not help.

It should be fixed by#116409.
