Overview
Many activities in IOService are asynchronous. When registration, matching, or termination is in progress on an IOService object, its busyState is increased by one. Change in busyState to or from zero also changes the IOService object's provider's busyState by one, which means that an IOService object is marked busy when any of the above activities is ocurring on it or any of its clients.
