Lots of devices don't need that delay, but enough of them do that we decided to add it. The value of 5 seconds was more or less arbitrary; it was long enough for every device we could test and it didn't seem _too_ long. Maybe 1 second would be long enough -- we just didn't know so we were conservative.
