Periodic scripts that hit external servers can cause a "thundering herd" problem, whereby many systems' periodic scripts run at the same time, and overload the server. To prevent this, such scripts should sleep for a random amount of time before hitting the external server. After r316432, there is a common anticongestion function to handle this. For an example of how to use it, see https://bugs.freebsd.org/bugzilla/attachment.cgi?id=181374&action=diff
