Thanks for the extra info @devnexen, and apologies for the delayed response. Revisiting this now (having seen it inactive for a couple of months) I feel it's still not clear whether this interceptor (and the one for `prctl` https://github.com/llvm/llvm-project/pull/124880 ) is important enough for the real-time programmer to outweigh the risks. I'd propose we close these two PRs for now, and re-open them later if there is renewed demand. @cjappl @devnexen how would you feel about this?
