Why can't we split harvesting entropy from /dev/random from harvesting
entropy from sources that are much more performance-sensitive?
Currently random_harvest_internal() is used for both and it is trying to
be fast, as we don't want to slow down the caller. But with /dev/random
the caller won't mind to be slowed down.
