That really depends on the system.  We can't assume that people are

people are using tickless kernels these days.  That's actually the
problem with changing /dev/urandom to block until things are
initialized.

Couldn't we disable tickless until urandom has been seeded? In fact
perhaps we should accelerate the timer interrupt rate until it has
been seeded?
