This also indirectly fixes the indeterministic build timeout on the master branch

If the process intercepts and handles the SIGTERM signal and doesn't exit, the parent process will wait until the child process has exited.

It should, but didn't

maybe we just need to avoid to use spawnSync in tests

It would be great if you could add a comment here explaining why we need this function instead of spawnSync / what issue it fixes.

It is an asynchronous version of spawnSync, with no special behavior. But preferred than spawnSync because spawnSync is unstable for unknown reason.

I think it would be better to add some explanation onto execReScript util you suggested.

Yes, we can do it there, too.

async function test() {

If we are already refactoring this, we could add a helper function in this file so that we can just write

const out = await execReScript(["build", "--help"]);

Can I separate it into a separate pure refactor PR?

Aside from the cli_help test, there are many other places to change.
