 That aspect is quite logical... Using a crontab entry means if the
script failed at some point for some reason, a fresh process will be
started 10 minutes later (give or take OS overhead).

 While an internal loop might support more precise 10-minute intervals,
if the script dies then nothing will be left running.


 For a remote sensor node that relays readings to another server, I do
think I'd want as many temporary files as possible to be running in RAM
disk, and not off the SD card.
