Abstract
A scheduler in a process of a computer system detects an execution context that blocked from outside of the scheduler while in a critical region. The scheduler ensures that the execution context resumes execution on the processing resource of the scheduler on which the execution context blocked when the execution context becomes unblocked. The scheduler also prevents another execution context from entering a critical region on the processing resource prior to the blocked execution context becoming unblocked and exiting the critical region.
