The kernel may be syncing a file system or doing something else that requires more time. So make the delay a bit longer, but provide some feedback and also grow the delay exponentially (though with a long exponent). If the kernel is doing something else, no need to repeat so often. With 38 attempts, we get a total of slightly above 5000 ms. I wrote this when I thought that the the delay is not long enough. It turned out that we were blocking the file system on the loop device, so waiting longer wasn't helpful. But I think it's nicer to do it this way anyway.
