What would it take to get number two to become a reality? Some sort of special module? This is the one main drawback I've found doing "production stuff" with Node.
Does Java offer cross-thread shared memory? Go, Haskell, Python, etc.?
Java does shared memory by default and even has concurrency related concepts as fundamentals of the language (Object.wait(), etc.) .
Python supports threading but is not very useful due to the infamous GIL. However, multiprocessing is usually a decent alternative and it supports shared memory on forking (copy on write, though). Also you can use mmap easily for IPC.
