Yep, absolutely corrrect. It was true at the lowest level (the semantics of fork) and it was true at the app/platform design level: in Windows you used threads inside a process, on Unix you used multiple communicating processes.
This obviously changed as pthreads came into being, and at this point, I suspect that the typical use for threads-sharing-memory and threads-not-sharing-memory is the same on most platforms.
A reminder that the task_t data structure describes threads and processes not just in Linux, but earlier Unixen also.
