In tracemonkey every jitted loop has such checkpoint to see if the script was canceled. Initially the worry was that it would very costly and the plan was to implement runtime code-patching to inject the checks only when necessary. But testing revealed that even with very tight loops the performance impact was negligible. _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
