Isaac, I just reread Ryan's announcement on the isolates feature (https://groups.google.com/forum/?fromgroups=#!topic/nodejs/eVBOYiI_O_A). At the time the word "thread" was not so horrible. Ryan was even talking about "debugging a multi-threaded node process".
The really critical point is not whether you go with threads or processes, it is the sharing semantics that you choose. If you go with "share nothing", threads and processes become "semantically" equivalent (maybe we can agree on this, at least). I think that threads are interesting because they are lighter (*) and they make (or should make **) it easier to implement zero copy. (*) a TAGG thread is just an isolate + a thread; a child node process is much heavier. (**) http://updates.html5rocks.com/2011/12/Transferable-Objects-Lightning-Fast What I don't get is why the word "thread" has become so horrible and is causing such reactions. To me share-nothing threads are just an optimization over processes. What matters is the "share nothing" semantics. I can understand that you consider threads to be a low priority on node's roadmap. As I said in my earlier post, the sweet spot of node is I/O intensive apps and these apps don't need this feature. What I don't understand is the irrational reactions that the word "thread" generates.
