+ Build System:
+ * Introduce the supernovae compilation mode
+   When compiled that way, the whole SimGrid (or almost) is put in a
+     single compilation unit and compiled in one shoot. 
+  This is to help gcc which has difficulties to inline stuff from one
+     file into another.
+  The speedup seem to be above 15%, althrough more tests are needed on
+     amd64 to confirm that gain.

+ * New SIMIX network module. Provides:
+   - Mailbox: rendez-vous mecanism to find with who you want to speak
+   - Synchronous send/recv: easier and hopefully faster since the
+     logic is handled in the maestro process directly now
+   - Asynchronous send/recv: you dreamt of it? It's here now
+     Too bad that nobody cared enough to propagate the change to MSG.
+ * Add semaphores as SIMIX synchronization mechanism.

+ Timing report of this version:
+  * Lazy evaluation brings arbitrary speedup (ie, speedup depending on
+    scenario parameters). From 8h to a few seconds in desktop grid settings.
+  * Supernovae brings about 25% speedup on i386.
