The Boost.Random engines seem to provide a seed overload that takes a 
generator, so it would be easier to just use that. But you should also keep 
in mind that this approach will result in 125 calls to sha1_random_digest 
each time an uuid_generator<> is created. This might not be acceptable for 
the typical case where the user only needs one UUID.
