Hi @thetruestblue,

I think ideally we would hunt down and figure out why this is failing to die. Both of the main RTSan devs work on macs primarily, and this test has always passed for us locally.

Is it possible to figure out what kind of lock is being taken by the 'not is_lock_free' large atomic, and intercept that? That would be preferable to disabling the test.
