It was random kernel module bug fixed long time ago (perhaps due to
furtune help :)
Speking in general, now even in the situation when absolutely no random
enthropy available at the call moment (very unlikely because of disks or
net etc. activity), kernel PRNG seeded with time, so plays not worse that
old time+getpid seeding used everywhere counting the fact that pids are
sequentual during the boot so it is better not relay on them.
