This does not make sense since we will invoke this callback twice. 2. This setTimeout code is assuming that, after the wait, there is still a callback in the queue. But this is not guaranteed since worker will continuously consume tasks from queue. So if the other workers are finishing their task, and consume next one, and if it gets exhausted when executing this setTimeout's task, then we hit an error 2011624 1 ysuzuki 2024-02-07 20:39:48 -0800 <rdar://problem/121879117> 2011625 2 ysuzuki 2024-02-07 20:41:29 -0800 Pull request: https://github.com/WebKit/WebKit/pull/24053 2011628 3 ews-feeder 2024-02-07 20:57:38 -0800 Committed 274265@main (dde5760b8dbf): <https://commits.webkit.org/274265@main> Reviewed commits have been landed.
