This would have to be for Meltdown not Spectre. Spectre is in process and meltdown is cross-process. In process would be pointless for a language like swift.

And it’s a weird mitigation because Meltdown afaik has been mitigated on other OSes without banning high res timers.

The nail in the coffin is that it’s unlikely about security is Date and clock_get_time are accessible and an order of magnitude faster.

This seems a more likely scenario of poorly profiled abstraction layers adding features without measuring the performance.
