Abstract
A system and method for providing mutual exclusivity to an operation is presented. A memory location is checked to determine if the memory location is subject to an exclusive lock. If so, the age of the exclusive lock is determined. If the age of the exclusive lock is greater than a certain length of time, the exclusive lock on the memory location is released such that operations can be performed on the memory location. When a memory lock is created, a length of time can be associated with the memory location. The length of time can be a default length of time. The length of time can be a custom length that is stored in a database. Other embodiments also are disclosed.
