Dunno what systems you folks use...
My ubuntu(s) 15.10 seem to (my estimates not hard data)
- update every couple of days
- kernel/security updates every 2-3 weeks

"Stable as the surface of the moon"??
Well thats strong
The other day I 
- aptitude purge-d the kernel I was running on
  [I was trying to show off to someone that ubuntu would not allow that!]
- machine kept running merrily but thereafter aptitude crashed
- Until I rebooted an older kernel; installed the one I had removed and rebooted to that
