🐛 Bug Report — SIGABORTs on macOS (JS heap OOM)

About once a day I get a sigabort in one of the workerd instances we use to run our product. It's very frustrating. Happy to help debug.

EDIT: seems like the issue here might be related to [many concurrent requests overwhelming workerd](https://github.com/cloudflare/workerd/issues/3120#issuecomment-2550952443)... that seems like its not good regardles.
