+========================================================================
+Il semblerait qu'il y ait un bug dans SG 3.5, et qu'on ne puisse pas
+utiliser MSG_comm_waitany() pour l'émetteur *et* le récepteur sans
+risquer d'interblocage.
+
+Le problème devrait être contourné correctement depuis le commit
+cd6b253 Use MSG_comm_waitall for communicator::flush(true).
+
+========================================================================
+Avec SG 3.5, les communications doivent être détruites dès que
+possible avec MSG_comm_destroy().  Si ce n'est pas fait, la simulation
+peut être extrêmement ralentie.
+
+Le problème devrait être contourné correctement depuis le commit
+404a8d5 Do not call flush automatically in communcator::send...
