My line of thought is that V8 is used in Node.js and in the browser, but 1 Gb is unlikely to be a problem for the browser any time soon, so it's really only a problem for Node.js. Am I missing something?
And technically the memory issue has already been resolved if you read the comments in the bug posting. The next GC release won't have any of these drawbacks. So really the problem is isolated to any node projects currently in production.
