809266a9fb Kernel: Remove tracking of bitmap memory.
There are no more kernel bitmaps. It's much better this way.

71b9ec1ae0 Kernel: Add basic process priority support.
For now, the WindowServer process will run with high priority,
while the Finalizer process will run with low priority.
Everyone else gets to be "normal".

At the moment, priority simply determines the size of your time slices.

5582a0a254 Kernel: When a lock is busy, donate remaining process ticks to lock holder.
Since we know who's holding the lock, and we're gonna have to yield anyway,
we can just ask the scheduler to donate any remaining ticks to that process.

41567c5bb9 Show the amount of memory in GraphicsBitmaps in /bin/top.
This seems like an extremely relevant metric to track.

c0cffe1134 Add a /bin/top program for process table monitoring.
It automagically computes %CPU usage based on the number of times a process
has been scheduled between samples. The colonel task is used as idle timer.
This is pretty cool. :^)
