+Fix a bug that causes the daemon to freeze when shut down with a signal like
+SIGINT or SIGTERM, and not with `mina client stop`. The frontier visualization
+debug diagram that is written at shutdown will now display a total_currency of 0
+for every mask. This functionality will be restored when the efficiency of the
+underlying operation is improved.
