I can imagine that the increasing process-creation time is due to beating on the memory manager. But why the increasing message-sending time as the number of processes increases? (Recall that exactly one process is runnable at any given time). I'm wondering if the scheduler is somehow getting overwhelmed by all of the non-runable processes that are blocked on Semaphores in SharedQueue. Any ideas? Vague from memory, and might confused things (we have tried too many different things here ;)): Shouldn't the standard interpreter VM remove the process from the scheduler list when it is waiting on a semaphore? I think, when there is only a single runable process for a given priority, then the list only contains that one.
