What is inqueue for?

One of the uses of the inqueue is to keep the status of a thread descriptor (not used, blocked or active). You can certainly get away without using inqueue, but you should make sure that you can still figure out what the status of a thread is. Remember that in Idle(), you have to print the status of all threads that are valid. Thus, if you choose to remove the inqueue field, make sure that you make the appropriate changes to the Idle() function given in the assignment so that it still displays the same output.
