I was able to get it to fail, but only by changing the sleep time to 0.01 seconds, and even then it took a few hundred iterations. At 0.02 seconds (or more) I could not get it to fail at all.
The fact that James sees MORE frequent failures with LONGER delays is exceeding strange. I'll give very long odds that he is not accurately reporting his experimental conditions.
