Since we currently have only the Giant lock it is unnecessary to use
other locking mechanisms. The introduction of fine grained locking will
be a major task.
For a G-EDF scheduler please have a look at:
If you use this framework it should be pretty easy to implement a G-EDF
scheduler. You only have to replace the priority queue with the
red-black tree operations.
