Further to this ... I was just doing some measurements to see how much
it'd add to backend startup time if we start using pg_strong_random()
to set the initial random seed. The answer, at least on my slightly
long-in-the-tooth RHEL6 box, is "about 25 usec using /dev/urandom,
or about 80 usec

I just noticed that, since I retired pademelon in August, we have
exactly no buildfarm coverage of --disable-strong-random code paths.
What's more, because the vast majority of the buildfarm enables
--with-openssl, we're mostly just testing the punt-to-OpenSSL
variant of pg_strong_random.
