Binding coding-system-for-read is definitely necessary.  I'm reading
random bytes, and I don't want Emacs to convert any of the values.  If
I don't bind it, `uuid-random' can return a list like:

(159 92 2210 119 150 148 2275 2265 2290 2220 2240 62 84 2235 150 18)

which is wrong, since it's not a list of bytes.

string-as-unibyte is probably unnecessary.

Uhm, I don't think there's anything strange about having to bind
coding-system-for-read to binary -- I _am_ reading binary data, after
all.
