Meteor 1.6.1.4 repo for reproducing issue with allocation bomb of fibers in Meteor 1.7+.
meteor npm install
meteor npm run start
Then open some browser tabs on http://localhost:3000 and observe the server console output report the number of fibers created.
Opening 5+ tabs (and having them visible on-screen to prevent your browser from throttling JS) will cause much fewer fibers to be created than in the corresponding Meteor 1.8.0.1 version of this example (here).
Used for meteor/meteor#10359.
