  I think I found the root of the problem, in /etc/init.d/mdev

mount_it()
{
        if fstabinfo --quiet /dev ; then
                mount -n /dev
        else
                # Some devices require exec, Bug #92921
                mount -n -t tmpfs -o "exec,nosuid,mode=0755,size=10M" mdev /dev
        fi
}

  I replaced "size=10M" with "size=50%" and rebooted.  It now works
properly.  Bug https://bugs.gentoo.org/show_bug.cgi?id=469226 filed.
