Eliminating Incidental Sharing

Sharing problems involving a task and a memory location are incidental if the memory location does not carry information into or out of the task. Therefore, if you replace all uses of the shared memory location in the task with uses of some non-shared memory location, you eliminate the sharing problem without changing the behavior of the program.

The following sections describe incidental sharing problems and their solutions.
