Ensure urandom entropy is of cryptographic quality.
The non-blocking PRNG /dev/urandom doesn't block if it has been seeded
enough, sadly (e.g., if the entropy pool is empty). Reading a few bytes
from the *blocking* should ensure that "the kernel RNG has [...] reach
full entropy at least once, which guarantees cryptographic quality of
the rest of the /dev/urandom stream." -- Tor bug #10676
