Is there a required condition? Always reproduces ### What is the expected behavior? Why is that the expected behavior? Expect that it loads the two import arguments, and then runs the file. ### What do you see instead?

It seems like it's getting stuck at: ``` // Sleep until worker responds. AtomicsWait(this.#lock, WORKER_TO_MAIN_THREAD_NOTIFICATION, this.#workerNotificationLastId); ``` I haven't been able to narrow it down to a satisfyingly minimal reproduction, and for extra :grimacing: it's order-dependent, but this will reproduce it in any project that has the latest tap installed: ``` node --import=./node_modules/@tapjs/mock/dist/esm/import.mjs --import=./node_modules/@tapjs/processinfo/dist/esm/import.mjs x.js ``` (where x.js is just console.log('hello')) 5 replies Jacob Smith [4 hours ago](https://openjs-foundation.slack.com/archives/C053UCCP940/p1701118050060099?thread_ts=1701105647.485299&cid=C053UCCP940) Oof. These are very difficult to troubleshoot. I think i'll have time on Wednesday to take a look (edited) aduh95 [3 hours ago](https://openjs-foundation.slack.com…
