Summary

Hi! I just updated to the latest ty version and updated my VSCode plugin, resulting in a huge memory leak and my home server going down. Minimal repro (thanks @dcreager).

The memory keeps ticking up until it takes 100% of system memory and the OS tries to kill it. This kill also failed, however, so maybe there should be a safety check to limit ty's memory usage to something reasonable.

I'm on Ubuntu 24.04 and running Python 3.13. The issue can also be reproduced on macOS.

Version
