The CPU Jitter Random Number Generator provides a non-physical true
random number generator that works equally in kernel and user land. The
only prerequisite is the availability of a high-resolution timer that
is available in modern CPUs.
Upon starting as a service, it will block until it has written 256 bytes
of entropy (which happens almost immediately)
