it's deprecated because it can't be used without races... basically it's
nearly impossible to use correctly!
Did you have a look in the kernel-2.6.18 tree how many drivers still
use interruptible_sleep_on() ?
not that many that are actually used hopefully; they're ALL bugs, with
maybe one or two exceptions who got lucky.
and the race can happen between the test if the process should sleep and
actually going to sleep?
