[Bug?]: Dev server builds break after multiple consecutive filesystem saves

[shivghai]

What's not working?

Happening to everyone on my team.

I don't know if this also happens with the web side [Edit - it does not], but if you save an API-side file consecutively (>10x times), the build loop for the dev server breaks and after this state, any changes to the api side aren't reflected in the running code.

This makes for a VERY VERY VERY painful dev experience.

The first error I see on server logs is this:

After that, any changes on the api side aren't reflected and we have to kill the server to have those changes be reflected. The server still runs with the old code.

This is very very consistent. I think this may happen with large Redwood apps (see https://github.com/redwoodjs/redwood/issues/9237 for another example of an issue that my team saw first, presumably because we actually have a large production app).

How do we reproduce the bug?

Save a file (I can 100% repro with API side changes) multiple times consecutively
