Also before that there's two FileException thrown because you use 
mkdir() systematically with a silent try catch. You should rather 
test if the the directories exist (when you create ~/.unde/  and 
~/.unde/bdb/, global_state.d) because it tends to be annoying 
when trying to get that stack trace for the real exception !
