Araq's recent post "A cost model for Nim" states that "Memory can be shared effectively between threads without copying in Nim version 2".
This is related to a problem I have been struggling with for a long time. Basically, the problem is this: * I have a program with two threads, A and B. * Thread A creates a ref object and of course owns this ref. * Thread A somehow moves this to thread B. (here lies the problem: how?) * Thread A no longer has any references to the object, an it is now effectively owned by thread B. My question is: how can this be done in Nim (or Nim 2), without violating the underlying C memory model? I can proved more technical details about approaches I have tried and what the problems are I run into, but maybe there just is a very simple and obvious solution I do not know about.
