The standard VM is using a single OS process (and thus uses a single core) but manages its own user land threads called Processes. The cool thing is that you can read/understand all this threading code (ProcessorScheduler, Process, Semaphore, Monitor, Delay, ..). There few if any limits to the amount of processes you can have.�
