Clemens Backes 9c5623c72e Fix data race in array sorting ... For copying the SharedArrayBuffer content, we cannot use a simple {memcpy} because that produces data races with thread concurrently modifying the content. Instead, use a custom {Relaxed_Memcpy} that uses proper relaxed atomics. The implementation is slightly optimized to do word-sized loads and stores where possible. If we still get performance regressions, we can optimize it further in follow-up CLs.
