test: use common/tmpdir in watch-mode ipc test
9ceac97 
Using `path.join(os.tmpdir(), 'file')` on a multi-user system can lead
to file collisions where the file already exists but is owned by a
different user and cannot be removed or overwritten. Other tests in
`parallel/test-watch-mode-files_watcher` use `common/tmpdir` instead
so switch to that for consistency.

Watch mode seems wonderful but I need a way to say I really want to exit without a restart. Is there an API or an option on Exit?

@BobFrankston can you kindly open an issue with an example describing your use case?

Since the documentation is sparse, I conflated **nodemon'**s automatic restart with the restart on change. I realize --watch may not only do a restart on change but not assure the program continues to run after failure. Both are useful but distinct. If it only restarts on change, then it's worth thinking about a --persist or related option.

test: use common/tmpdir in watch-mode ipc test
86bdcf3 
Using `path.join(os.tmpdir(), 'file')` on a multi-user system can lead
to file collisions where the file already exists but is owned by a
different user and cannot be removed or overwritten. Other tests in
`parallel/test-watch-mode-files_watcher` use `common/tmpdir` instead
so switch to that for consistency.

Maybe it would be good to add the ability to handle multiple entry points?

I am experiencing an issue where on some restarts, it seems watch mode restarts constantly for up to about 60 seconds - Eventually it recovers and runs normally.

I'm running on Windows 11 x64, Node v19.8.1 (not quite latest). Process Explorer confirmed that it was rapidly restarting and making 100s (or 1000s) of new processes that were dying quickly. My app does not modify local files. I believe my editor is also not repeatedly editing files.

I'm not even sure where/how to start debugging this... I should probably make a new issue.Uuntil I pull all the details into a real issue, this will have to suffice ;)

@mule-stand Running node ... is by definition one entry point. What are you imagining would change? In any case, this discussion would probably be better in a new Feature Request issue.

@BobFrankston You can add an infinite sleep at the end of your own program to keep node alive and watching for changes. This is what nodemon does internally. You need some process still running to be notified of any changes to the file system. You might even check process.execArgv.includes('--watch') and only run the infinite sleep if watch mode is enabled.

@cinderblock Please open an issue. This PR is not the right place to discuss such problems in depth.

@cinderblock Did you open an issue for this restart thing? I am facing the same issue with Win 11 and Node 20. I try to reproduce this with a small code example, but it is kinda random and I don't know what causing the issue.

Edit:
After some research I found out that fs.watch is reporting change events when a file gets read. I opened an issue for this: #50920
