## What changed? Use PrioritySemaphore with n=1 instead of priorityMutex in WorkflowContext object. ## Why? PrioritySemaphore has much lower memory usage compared to PriorityMutex. We will create a WorkflowContext object for each workflow in WorkflowCache. We can save a significant amount of memory from this. ## How did you test it? Unit tests. ## Potential risks None ## Documentation ## Is hotfix candidate? No
