Yeah, I once accidentally spawned off over 10 threads by using a regex search in Visual Studio and they lived for over a half hour, so I'm now overly cautious.
The type checker I'm working on uses workers, so I could possibly detect it and kill the worker.

The language server process is always killable, but I think it's still pretty undesirable for something that easy to run into. I could imagine regex types that aren't as powerful as actual regexes.

You could do so much with strictly regular regexps. Another bonus: matching is simpler and way more efficient.
