🐛 Bug Report — failed: connect(): Cannot assign requested address; address = [::1]:44563

This bug is preventing me from being able to send multiple requests to a wrangler dev instance. The first one goes through fine, but any further requests are blocked by this error.

Along with this bug, the workerd process will be stuck using all of the CPU avalible.

Heres some logs in case these are useful:

```
