 I can only see that one occurring if there are concurrent page loads,
 personally.

 One trick could be to set a transient that expires after a minute before
 the cron starts; and then to check if the transient is set before running
 the cron at all. This would introduce some level of throttling. Even then,
 though, we'd potentially get dup crons on a site with really heavy traffic
 if two concurrent page loads try to add the transient.
