Guessing from the names, is this what these directories are for?

  $SUGAR_ACTIVITY_ROOT/data   # contents preserved after exit,  
private to one activity instance
  $SUGAR_ACTIVITY_ROOT/conf   # contents preserved after exit, shared  
with all activity instances
  $SUGAR_ACTIVITY_ROOT/tmp    # contents deleted after exit, private  
to one activity instance

I started documentation for this at
