> What is it actually waiting for? This is a valid file according to the sample solution.
A process calling wait will be blocked until all of its child processes (that it has spawned) have terminated. The project sheet says: "waits for all processes that it has spawned to terminate (at which time the process is marked as Blocked until the other processes terminate)."
> And am I correct in saying that if wait is called with nothing to actually wait for then it just goes back to the READY queue?
The Clarifications page says: "If a process calls the 'wait' system-call when it has no children, it should be moved from the CPU to the READY queue (not to the WAITING queue)." If either of these points are unclear, please explain which part you're confused about.
