Would be quite nice if crontab -e did something to avoid concurrent sessions with the last one silently overwriting any previous changes.

Issuing a warning if a file has been changed since reading it in (by comparing temporary and spooled file timestamps) should be good enough:
* check out spooled file for editing while saving its timestamp
* edit
* check saved timestamp against current spooled file's one
  * issue a warning if it's older already, or
  * check edited file into spool

PS: yes I just [almost] did fall to this one. :)
