Key Features

1. a branch entitled "zen-tune" was added - this branch implements four tunable profiles, defaulting to desktop - only adjusts 4 things so far

Server Settings: dirty_ratio: 80, dirty_background_ratio: 1 --- BFS rr_interval and iso_cpu are left at default
Default Settings (nothing changed): dirty_ratio: 20, dirty_background_ratio: 10, *BFS ONLY* sched_iso_cpu: 70, rr_interval: 6
Desktop Settings (selected by default): dirt_ratio: 50, dirty_background_ratio: 20, *BFS ONLY* sched_iso_cpu: 25, rr_interval: 3
Custom Settings: Enables another menu which allows for each to be set manually - also has descriptions for each variable from the documentation

2. The "classic-rcu" branch from zen.git was pulled into a new branch, but:

The preempt rcu implementation is dropped totally
The classic rcu implementation is changed to match the implementations of 2.6.33 tree rcu and tiny rcu, instead of 2.6.31 classic rcu
Several compile errors have been fixed, probably due to one or both points mentioned above
Classic RCU will probably replace tree_rcu in the default zen spot after this release (if no bug reports, will become default in zen2)
