Abstract
Two or more processors that each provides a specified thread to access a shared resource that can only be accessed by one thread at a given time. A locking mechanism enables one of the threads to access the shared resource while other threads are retained in a waiting queue. Responsive to an additional thread that is not one of the specified threads being provided access the shared resource during an identified time period, and responsive to a first criterion an a second criterion being met, the additional thread accesses the shared resource before the other threads in the waiting queue.
