The big problem isn't cron, it's atrun. Some years back I started
converting atrun into its own daemon, to allow it to wake up only to
run jobs instead of being fired off regularly and spewing syslog
messages. I don't remember what happened to the (half-done) patches
but if anyone wants to take it up I can probably find them.

still, being able to turn certain things off while running on battery
is a good idea.

...and doesn't syslogd have some voodoo so one can tell it not to
fsync each and every message?
