Abstract: A sleep function capable of putting a fixed high-priority thread to sleep within a time-window is disclosed. After a sleep request has been made by a fixed high-priority thread via the sleep function, a determination is made whether or not the fixed high-priority thread is awoken before a requested sleep duration under the sleep request. If the fixed high-priority thread is awoken before the requested sleep duration, the number of tasks for the fixed high-priority thread to perform is increased in order to delay the start sleep time of the fixed high-priority thread from a point within a first time-window in which the sleep request was made to an end boundary of the first time-window.

Abstract: A program executing on a computer system implements a soft protection by allocating a region of memory in the computer system, initializing a soft protection on a page in the region of memory, detecting a use of the page having the soft protection, receiving a signal from an operating system executing on the computer system, and determining if the signal is masked off. An operating system module executes on a computer system for implementing a soft protection. The operating system module includes an initialization module for allocating memory, a settings module for saving a previous soft protection setting, a detection module for detecting a page fault, and an execution module for setting a notification signal, clearing the soft protection and restoring page permissions.
