++// When we changed from the old dbm database format to the newer sqlite
++// implementation, the upgrade process left behind the existing files. Suppose a
++// user had not set a password for the old key3.db (which is about 99% of
++// users). After upgrading, both the old database and the new database are
++// unprotected. If the user then sets a password for the new database, the old
++// one will not be protected. In this scenario, we should probably just remove
++// the old database (it would only be relevant if the user downgraded to a
++// version of IceCat before 58, but we have to trade this off against the
++// user's old private keys being unexpectedly unprotected after setting a
++// password).
++// This was never an issue on Android because we always used the new
