sentry-domain-memory-leak

This repo contains a reproduction of an issue related to getsentry/sentry-javascript#7031.

Reproduction instructions

Clone the repo and run yarn install
Run docker pull ubuntu
Run node --inspect index.js
Attach a debugger and look at the memory consumption; it should be ~10MB.
Make a request to http://localhost:80/ in your browser.
Look at the memory consumption in the debugger; it should be about 300MB and should stay that way even after manually triggering a garbage collection.
Stop the server, remove all Sentry-related code from index.js, and repeat the above steps. Note that memory consumption should fall back to ~10MB either immediately or after triggering a garbage collection.
