Correction d'une réinitialisation sauvage de la pile des variables par niveau
dans la copie de la structure de description du processus. Cela corrige
la fonction SPAWN qui échouait sur un segmentation fault car la pile des
variables par niveau était vide alors même que l'arbre des variables contenait
bien les variables. Passage à la prerelease 2.
