When we have a completion promise, which will in its turn be resolved/rejected with the resolve/reject value again, we call once again crossThreadCopy on the value as it's using a common code path for resolving/rejecting it. We could easily distinguish the case from the standard resolve/reject and not call crossThreadCopy() then (though this one is mostly a no-op as we are simply moving the value) 1982618 1 webkit-bug-importer 2023-10-04 15:40:55 -0700 <rdar://problem/116489817> 1982667 2 jean-yves.avenard 2023-10-04 18:01:34 -0700 Pull request: https://github.com/WebKit/WebKit/pull/18664 1983679 3 ews-feeder 2023-10-09 07:54:48 -0700 Committed 269075@main (0e9b295049f8): <https://commits.webkit.org/269075@main> Reviewed commits have been landed.
