[Sysadmins] Timing automated batch jobs ...

For some reason, I keep coming across the pattern of cron jobs that
have "sleep $RANDOM % 3600" in them - in a vain attempt to spread
load. It's a really harmful dangerous pattern, it annoyed me so much,
that I've written about it ;


If anyone comes across this pattern, do me a favour and send me the
details, I want to start squashing these bugs. I've opened a number of
problem reports already with various Open Source mirroring and update
scripts, with various degrees of success.
