Description
Description
Make an option, in flags or command-line, to allow users to increase or remove heap memory limit, to use heap larger than 4GB in systems with much greater memory.
Who's implementing?
- I'm willing to implement this feature myself
The problem
Currently chrome limits the heap memory (or the memory of a render process) to likely 4GB, but larger heap would be useful for debugging heap using the memory profiler, or running large, resource-consuming app on web. This is previously discussed on many forums, but now I can not find a thing that works without rebuilding the chromium itself.

Possible solutions
- Make the flag
--max-old-space-sizeand--max-semi-space-sizework like in node.js - Make a flag to disable pointer compression (this could be a compile-time flag)
- Get things upstreamed
Alternatives
Use Firefox which has larger limit on heap, and a slower js engine.
