I know, of course, that Java green threads and Haskell forkIO threads are called "threads", but I personally believe its misleading to call it concurrency -- they're not doing more than one thing at a time.
Aren't you thinking about Parallellism?
No.
http://en.wikipedia.org/wiki/Concurrency_%28computer_science%29 In computer science, concurrency is a property of systems which consist of computations that execute overlapped in time
You're not doing anything simultaneously ("overlapped in time") when you're using poll and select (only). To do something simultaneously in Unix, you'd have to either use fork() or start a thread.
That was his point. Threading is a way of structuring a program. Parallelism is a strategy for exploiting that structuring (and others). -- Aaron Denney -><-
