The upgrade process updates GcUser's configuration parameters. Any configured
value for #sleepTimeBetweenReclaimMs was not preserved by upgrade.
On upgrade from version 2.2.4 or earlier, it would be set based on the
previous value of #sleepTimeBetweenReclaim; upgrades from later versions
would always result in a setting of 0.
Reset the configuration parameter manually after upgrade.
