Non programmer here, but would it make sense to add a keyword (or flag) to Go to manually allocate a piece of memory (ie not use GC). That way, for some use cases, you could use avoid GC for the critical path. Then when GC happened, it could be very fast as there would be far less to pause-and-scan (in this use case example). Obviously this would have to be optional and discouraged...but there seems to be no way to write an intensive real-time app with a GC based language. (again non-programmer that is writing this to learn more ;-)
