If you don't mind doing a *busy* loop (which might or might not a bad idea, depending on application), you could take the requirements literally: Before starting the external program, you remember the value of time(). If you found that during the last three executions, you already had recorded the same time value, you just busily loop until the time value increases.

Of course I can imagine circumstances where you will be shot doing this programming style, but this is something you can best decide yourself.
