--- Comment #18 from Stephan Tobies <stephan at tobies dot info> --- +1 - I have a use case where a QuickThread is migrated from one pthread to another. TLS would need to be re-fetched after this migration, but is not due to CSE optimizations. Having a way to disable this optimization, either locally or on a per-file basis would be very useful!
