It speeds up the initial seeding of gpg and gpg-agent's the internal
RNGs if the system's entropy sources is slow.  These days it is of less
use and in some cases a

echo only-urandom >/etc/gcrypt/random.conf

might be all what is required to speed up things.  Note that this
affects all processes using Libgcrypt so it might be advisable to clear
this right at system startup and set it only after the early boot
phases.  YMMV
