Abstract
An operating system for a computing device includes a scheduler incorporating an algorithm for ordering the running of threads of execution having different priorities. The operating system is also arranged to provide a list of threads which are scheduled to run on the device, ordered by priority. At least one locking mechanism for docking access to a resource of the device from all threads except for a thread that holds the locking mechanism is also provided, and the operating system arranges for a scheduled thread which is docked from running because the resource it requires is locked to cause the thread which holds the locking mechanism to run.
