Synchronizing access to a shared resource utilizing selective locking

A method and system for providing access to a shared resource utilizing selective locking are disclosed. According to one embodiment, a method is provided comprising receiving a request to perform a resource access operation on a shared resource, invoking a first routine to perform the resource access operation, detecting a data processing system exception generated in response to invoking the first routine, and invoking a second routine to perform the resource access operation in response to such detecting. In the described embodiment, the first routine comprises a dereference instruction to dereference a pointer to memory associated with the shared resource, the second routine comprises a lock acquisition instruction to acquire a global lock associated with the shared resource prior to a performance of the resource access operation and a lock release instruction to release the global lock once resource access operation has been performed.
