Yeah. I didn't understand the need for the perfc stuff. Are there
Windows systems that don't have the Crypto APIs? I doubt it, but the
buildfarm will tell us in a moment if there are.
And if we don't have a good source of randomness like /dev/random, I
think it's better to fail, than try to collect entropy ourselves (which
is what unix_std did). If there's a platform where that doesn't work,
someone will hopefully send us a patch, rather than silently fall back
to an iffy implementation.
