/dev/urandom is a symlink to /dev/random.  Neither will block, because
we explicitly mark /dev/random as seeded with a SYSINIT late in the boot
(not as late as I'd like, but not too early either).

If you mean the device attach entropy gathering, that was a case of
parallel invention from Pawel and myself, where I ended up using Pawel's
patch with minor modifications.
