- Updated sleeping paths such that a task is atomically put into a runqueue and made RUNNABLE, or removed from a runqueue and made SLEEPING. - Modified vma dropping sources to handle both copy_on_write() and exit() cases in a common function. - Added the first infrastructure to have a pager to suspend a task and wait for suspend completion from the scheduler.
