generic/192 would sleep 40 seconds, update a file's atime, and then fail if the atime was not exactly 40 seconds later. This is unreliable since things may be slow enough to cause an extra second to elapse. "Fix" this by allowing for 2 seconds of delay. Also, while we're at it shorten the sleep to a much more reasonable 5 seconds.
