For the macos-x64-debug builds, the overwhelming case is the unmounted case, so Continuation::getStackTrace, e.g. in one run there are 15 million samples where the target is unmounted, 13k samples when the target is mounted, and 14k samples where the target is in a transition state so its stack trace can't be sampled and has to be retried. When unmounted, the target is disabled from being scheduled so this is why it makes such slow progress on some of these test machines.
