For apps which know they're accessing cd or dvd (probably using sg
commands), asking for TUR test after resume could be acceptable but apps
getting -EIO on read(2) because of intervening suspend/resume cycle is
just not right.  The problem is that readiness waiting can take quite
some time and under the current architecture, that can make resume take
much longer or block IOs to other devices on the same port.  :-(
