(Get the code!)
Lennie,
I finished rebooting "a few times" and here's a histogram of what I've got.
It basically falls into 3 categories: less than 100ms (majority of cases), about 600~1000ms and close to 2000ms. I could not get anything >2 seconds, which is a good sign.
Given the wide range I would suggest starting the usleep value at 20ms and multiplying it by 2 every time it fails, with the max delay of 1 sec (what do you mean I'm going to 11? ;) ). That way we keep a good reaction time without polling hundreds of times. So we would check at the following accumulated times: 0 (first retry), 20, 60, 140, 300, 620, 1260, 2260, 3260,..., 10260. If it fails after those 10 seconds then we should have a phatt warning in the logs. A debug message telling the total time of the waiting loop would be nice too (if the loop is triggered, of course)
