/dev/random doesn't hang (usually...), though I understand and agree
with where you're coming from.  

For gnupg2, version 2.0.26 on Devuan* (note, I moved the binaries and made a
symlink between /usr/bin/gpg and /usr/bin/gpg2, because I always forget
to call 'gpg2' outright), this is what it says:

| generator a better chance to gain enough entropy.



* Devuan Jessie = systemd-free fork of Debian Jessie.  Support init
  freedom :)
