I had trouble like this with the YP stuff - if two people changed their passwords or something at the same time, etc. I put my own locking in so that if something is in process it doesnt even try to run. if it were me - I would change the method to create a file of pw commands, that a cronjob checks for an executes evern so many minutes IF a lockfile doesnt exit (so worst case it takes an extra 5 minutes before an account is created).
