From reading the docs, it sounds like forkIO keeps everything in a single OS thread/process. Doesn't this mean that a program that uses forkIO instead of forkOS loses out on SMP machines?
You can use e.g. +RTS -N2 to use 2 OS threads.
That's rather ugly though, and doesn't "just work". With other languages, I could just use OS threads, and let the OS schedule, say, 15 threads across 2 CPUs, or 4 CPUs, or however I may have. -- John
