Log:
- Enable NT Scheduler.
- The good:
  - Fixes hangs/freezes in trunk
  - No matter how sluggish the system got, I was able to move the mouse and other apps
were still responsive even though one app was hogging the CPU.
  - Balancer thread activates and does its job of preventing deadlocks.
  - The code was heavily tested and some of it is based off direct pseudo-code from
NT's very own kernel (legally obtained from Windows Internals II slides) as well as
Windows Internals 4th.
The bad:
  - Explorer takes 30 seconds to load, after that all is fine though.
  - First-stage installer asserts at 18% in Mm instead of lagging like previously.
  - Various other Mm crashes related to the above ^^.
- Please help out to fix/figure out the Mm crashes! It would be much appreciated,
otherwise, in a week, we will revert this patch as well as the patch that caused the
hangs/freezes.
