The task_resume function decrements the suspend count for task. If the task's suspend count goes to zero, the function resumes any suspended threads within the task. To resume a given thread, the thread's own suspend count must also be zero.
An attempt to lower the suspend count below zero is ignored.
Only generic errors apply.
