* Change the correction factors used in LMM model, according to
the lastest experiments described in INRIA RR-7821.
Accuracy should be improved this way.
+ (TODO: this is not true in the code, yet)
* Use the partial invalidation optimization by default for the
network too. Should produce the exact same results, only faster.
* Major cleanup in surf to merge models and split some optimization
* Use now crosstraffic keyword instead of the terribly missleading
fullduplex keyword. It is activated by default now in the current
default model, use --cfg=network/crosstraffic:0 to turn it off.
+ * Ongoing refactoring the model parsing to make XML files optional
+ (more work is needed here to fully achieve this goal)
Simix:
* Stabilize the parallel execution mode of user contexts
