  • allocating a memory address of a lock value for a resource lock, the lock value corresponding to a state of the resource lock;

    retrieving the lock value from the memory address;

    yielding by a first thread at least a portion of the processing resources for another thread if the lock value indicates the resource lock is unavailable;

    checking the lock value at the memory address in response to a switching event; and

    acquiring the resource lock for the first thread if the lock value indicates the resource lock is available.
