Updated test0 with a forktest. Fixed timeslices. Updated kmem usage calculations.

Browse Source 
- 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.
