I think the problem with the sleeps is simply the sleeps. My original plan 
to put my sleep/fetch in the background was shot down by some who thought 
it wasn't simple enough.

Secondly, we don't need sleeps every boot. Ntpd for example only needs a 
sleep twice a year max to fetch a new leapfile so, to have a sleep every 
boot would be annoying.

The best solution to replace sleeps would be to put a list of files:URLs 
into a queue to be fetched by fetcher script which would fetch only needed 
files that boot (or in the case of ntp via periodic.conf twice a year).

A single script with a queue of files to fetch with one anti-congestion 
sleep, preferably in the background.

NTP, btw can (will) use the leapfile in /etc/ntp until a fresher copy is 
fetched.

Let's remove all fetching functions from the various rc scripts and queue 
them up early in a fetcher rc script, preferably in the background if at 
all possible.
