- test0 now forks 16 tasks that each modify a global variable. - scheduler now gives 1/10th of a second per task. It also does not increase timeslice of a task that has scheduled. - When a memory is granted to the kernel, the distribution of this memory to memcaches was calculated in a complicated way. This is now simplified.
