What steps will reproduce the bug?

code:

console.log("hello world!");

run this with node --watch=true index.mjs. (can also reproduced with --test flag).

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

simple behavior same as with node --watch index.mjs.

What do you see instead?

Additional information

Edit: Maybe passing watch flag as --watch=false is wrong way, but an infinite loop is not something I was expecting :/

Edit: More in dept, i figured out it is not related to test_runner.
