	I don't have a strong opinion either way ... I'd prefer us to not have
any UUID generation code of our own at all since we'll inevitably have
the rfc4122 zealots coming down on us, but we'll always have to have
that code, so ...

	I didn't optionally use uuid_parse() for the exact reasoning you
describe, but I think that reasoning is less important for UUID
generation since we're effectively treating them as opaque random
numbers.

	You're happy with the other two patches, then?

Cheers,
Mark.
